I had a 98 VW jetta named Gunther, but that’s the only car I’ve given a name to. Right now I drive a silver 94 celica, which I like a lot but it’s too bland to really inspire a good name. I do like named cars, though. I should try to think of one.
My '94 Dodge Spirit was named, “El Espirito”, capturing it’s evident Spanish flair and zest.
My '99 Dodge Stratus was officially dubbed, “Spartacus the Stratacus”, but answered to Sparty.
I currently drive a '04 Toyota Matrix, which is named, and you MUST say this angrily, the “EIGEN VECTOR!!!”
1983 blue Toyota Tercel - the Blue Dragon, stemming from a misunderstanding with my mom over a book title (she said she was taking The Blue Dragon to the library, and for some reason I thought she just meant the car)
2003 royal blue Beetle - the Smurfmobile. Both for its color and the fact that the nickname that I haven’t been able to shake for 22 years is Smurf. I guess that makes all my cars Smurfmobiles by default!
My brother’s white Camero was known as The Ghost.
DH called his Mini Cooper Stewie, after the kid on Family Guy, both for his accent, and the fact that we’re reasonably sure that if we had kids, we’d have Stewie.
My mom’s purple Geo Metro was the Jelly Bean for its shape, or the Metallic Grape (I think that was the paint color’s name).
'88 ford escort pony (black paint, 1.9L, 85HP of four cyl. fury, four speed manual (ford was too cheap to put a fifth gear in the transaxle) ) originally was ironically named “Blackbird” after my favorite aircraft, the SR-71, even though it barely had enough power to get out of it’s own way, let alone break the sound barrier, but after 4 years with that piece of fei-oo, it garnered a NEW name…
“The Murphy’s Lawmobile” (you name it, it broke)
'92 Dodge Shadow America (Red, 2.2L Four, 98 HP 5 speed manual); I don’t remember what I named this one, or even IF I named it, it was a good car though, got 120,000 miles out of it before I traded it for a;
'98 Dodge Neon Highline (Red, 2.2L 132HP, 5 speed manual); “Vlad” after Vlad Tepesh (Vlad the Impaler), mainly due to it’s blood-red paintjob, another good car, also got 120,000 miles on this one, traded for;
'02 Dodge Neon (Steel Blue, 2.0L 132HP, 5 speed manual); TARDIS, it was a dark grayish blue, and was bigger on the inside than the outside, sadly, this car died early at around 98,000 miles due to a rusted-out front suspension Subframe assembly, a part that my ex-mechanic missed every time he had it up on the lift for a tire rotation…
my current car is a '07 Saturn Ion Level 2 (Berry Red, 2.2L, 145HP, 5 speed manual), I have less than 8,000 miles on it, it got it’s name “Phoenix”, after it saved me from injury in an accident two days after I had taken delivery of it, the Saturn spaceframe really does work quite well, the car was repaired to factory spec, and you could never tell it was in an accident, perfect repair job
ironically, no less than a month after I had my accident at at that well known dangerous intersection, the town put up a blinking yellow “caution” light over that intersection, apparently no less than a week after my accident, another accident occurred there…
it’s a flat, level road, with a four way intersection, it’s common for some drivers (read, idiots) to sit at that intersection waiting to turn, with their foot off the brakes, no brake lights, no turn signal, just…stopped…
I had an early-eighties Nissan Sentra, a car with chronic fuel pump problems. I saw the film “The Gods Must Be Crazy” in which there was a Jeep called The Antichrist, and I applied that name to my Sentra.
My 1986 Toyota Van I called…
The Kitemobile
Great vehicle for carrying all my kite stuff all over the place!!
I called my '76 Corolla 5-speed Studmuffin
It had switches for rocket launchers, buttons for front machine guns, and a seat eject switch. 
I chuckled a little. 
My first car was a '72(?) Fiat Sedan. Don’t let the “Sedan” fool you, it was a tiny car. I named it Topo Gigio, after the Italian mouse on the Ed Sullivan show (I know I am dating myself here). I loved that car. Some idiot accordioned it by not watching where he was going and slamming me into another car. The other cars were big monsters and were barely scratched.
I drove other cars belonging to the family but none were mine. My grandpa’s American Rambler that I drove for a while was called The Mac Truck because it drove like one. I had a really crappy POS Datsun for a while that leaked fluids so bad I always had to carry brake fluid, clutch fluid and oil with me to refill as needed. I called it a lot of names.
Then I had a Toyota pickup, my first car I bought myself. I just called it The Truck.
I still wasn’t over Topo Gigio and not up to giving the truck an actual name.
Then I got a Lumina APV minivan. It looked like a shuttlecraft from Star Trek:TOS, so I called it Gallileo.
Now I have a Matrix. I call it Neo. I know, not very original but the name ends in “eo” which links it to the previous vehicle and I liked that idea.
My first vehicle was a '67 Chevy C-20 named Teddy Roosevelt (or just plain Teddy) because it was a rough rider.
Most of my vehicles have been named, a lot of times just because they looked like a Ralph, Maude, Matilda or Betty Jean. My last pick up truck, though, was called Pinky the Cat.
Originally, it was called Pinky for the pink squiggly lines of it’s decorative stripes. After being several times, the Cat was added for its many lives.
The first car I bought was Tomatito (little tomato) because it was red and the smallest model that particular make sold at the time.
The first car I’d driven at home was El Anciano (the ancient one) because, well, it was archeological.
The first Yaris I bought and which my brother now drives is just *el verde * (the green one) while the second one is sometimes referred to as *el de camuflaje * (the camo one) because dangit, it sometimes seems as if every other car in any given parking lot is also grey!
Dad had an orange one which was Calabaza (Pumpkin) because a) that was the official name of the color and b) it was the closest we’ve ever come to having a lemon and nobody in my family likes pumpkin.
We currently have a Jeep Cherokee Country and the BF calls her “The Beast”.
My dad owned a Ford Granada that he used to call the “Granola Bar”.
My first car - an ungly dark brown 1970-something Honda Civic hatchback that was used at a farm for towing so it had 2 small mirrors mounted on each side near the front end… it looked like a freakin mechanical bug… so it was dubbed: the Roach/Cockroach, roach-mobile, or sometimes Japanese Cadillac. sighs It was a great car despite the ugliness. Manual transmission, bucket seats that laid all the way back, and took cheap regular gas and got pretty damn good mileage despite its age.
Jezabel was my second car - red, 1978 2 door Nova. It was always getting me into trouble (it liked to go fast).
Had a couple other cars before my latest, but dont recall their names. My recent and most beloved car is a silver 4-door Honda Accord '99 which I simply call “my baby”. It has been the best car I have ever owned and has never broken down - I’ve had to replace a few tires and batteries, but thats it.
In order of ownership:
80s vintage Dodge Diplomat - Uriah Heap (spelling intentional)
91 Chevy S10, all black - The Hostile Amishman
02 Chevy Trailblazer - The Family Truckster
97 Mercury Sable Wagon - The Nerdmobile
Currently owned:
91 Chevy Beretta, red in color - The Foomobile (obscure joke reference for those who like a challenge)
85 Ford F150 - depending on my mood, The ShitBeater or The Dump Truck
I don’t generally name my cars, but my first new car, a 1974 Ford Gran Torino, became the Starsky & Hutchmobile because it looked just like their car.
The car I bought after that, a 1980 Oldsmobile Cutlass, became known as Christine, because, damn, that freaking car was POSSESSED. It spent more time on the back of a tow truck than I spent driving it. I was sooooooooo happy to make it go away, even though it cost me several hundred dollars to replace the AC condenser that broke between the time I sold the car and I was actually going to get rid of it. That car was EVILE.
My hubby, Dave, had 3 Beetles back in the 70’s he called Beowulf. The Pontiac Laser he had when we first got married was The Red Sled because before we got ice tires for it, if you hit a slick spot on the road, it would turn into an Olympic bobsled!
Our current car, a Subaru Legacy, is called Subitu. [Subaru #2]. The car before that was an older model Subaru Legacy that we called Subee. When it got wrecked and we replaced it with this car, it became Subitu.
My first car was called Blue Beluga because it was a light blue and HUGE. It was a boat and a half. The car following that was Baby Blue Beluga [smaller car, same color] and its successor was You Fried Up Piece of Shit, although I have no clue why.
I’m guessing it put out a bunch of smoke? 
First car was a green Civic named Royal. Nickname was usually Buddy.
Current car is a red Corolla named Digby. Nickname is usually Buddy.
My first car was a massive 1979 Chrysler Cordoba. It was called the Behemoth by all - until it was damaged by an 18-wheeler. (ah, if only the frame hadn’t been dented…)
The bicycle I rode allot after that was Frankenstein, because I kept on cobbling together bits and parks from other bikes.
No other vehicle I’ve had since has earned a nickname.
My now ex step daughter had a knack for picking out nicknames for our cars.
90 Honda CRX- Buzz A very apt name.
86 Honda Accord- Cold Blue This car had an air conditioner that almost was delivering ice cubes.
90 Honda Civic - Trixie perfect name, it just worked for that car.
The '99 VW Pissant (Passat to you).
Still the greatest damn car I’ve ever driven. Fast, reliable, comfortable…if I didn’t have to load CDs into the trunk, it’d be perfect.
