When in the process of buying my current car (a Subaru Outback Sport), my SO repeatedly referred to it as Scooby-Doo. He said he knew someone who owned a Subaru back in HS or some such and that’s what she called her car.
Hmph. Not one to live in someone else’s shadow, I bought a tiny stuffed MewTwo and attached it to the rearview mirror. My car is the Mewbaru. 
My '92 Honda Civic is named Red. The '01 Civic is not named yet.
Most of my cars have been unnamed, just a couple of exceptions. I had a Volare I named Christine because it frequently did things on it’s own (like shift gears and honk the horn), and an old Colt station wagon I named The Killer Tomato because of it’s color.
My current car is unamed, doesn’t really deserve it, but my last car, a '86 RAM 50 pickup ws named Boris ala Rocky and Bullwinkle. It was short, dressed in black and comical too.
My 1990 XJS is called “The Laura-mobile.” As were all of my previous cars.

You drive a Jag?! Cool! It’s my favourite car which I never bought… I keep putting it off for one reason or another.
All my cars are lovingly refered to as “Shitboxes”. Not because they are. They’re not. All are fine euro sedans which I keep in pristine condition. All still under warranty. It’s just a game an old friend of mine and I play. Long story…
My first car, a graffiti-adorned slant-six Valiant, was named (and inscribed, in 10-inch red letters) “The Capitalist Tool”, in homage to Malcolm Forbes.
My current '65 Mustang is the “Big Woo”. Just short enough for a vanity plate, too.
My old girlfriend named her two (now wrecked) Alfa Romeo Spider Veloce convertibles Guillermo and Bella. We broke up, she took the car, and moved in with the Alfa mechanic.
But the really apt, spontaneous names go to my friends cars, including:
Skippy ('85 Festiva)
Otto ('83 VW Golf. Crap on wheels).
The Rocket Sled ('84 Celica)
Emperor Hirohito II, “The Emperor” for short ('87 Supra)
My car is named the Abelian Grape. Guess why.
You want car names? I’ll give you car names…
Sherman = '76 LTD family car (da tank)
Katana = 1970 or so Toyota Corona. (play on hebrew word for “little”…didn’t realize at the time that it was a killer Japanese weapon. Bet the car knew though.)
Mycroft = my first car, 1982 Honda Accord (the computer in
“The Moon is a Harsh Mistress,” I seem to remember)
Edward Tudor = my next car, 1986 Nissan Sentra. (As distinguished from previous cars, which were all Fordors.)
Triple B= 1982 (or so) Mazda 323, boyfriend’s car with a Big Blue Butt. Yes, the car, not him, duh.
Da Heap = The Jeep
And, my husband’s pride and joy, the ultimate step up from the Triple B…our Mercury Grand Marquis, which he lovingly refers to as “The Grand Pooh-bah” (or simply “the pooh-bah”) and I call “The Geezermobile.”

My '93 Lumina is named Jasmine.
My ex-girlfriend named it back when we were going out. Somehow I kept on calling it that.
This got me a really weird look from a girl on a first date once. She didn’t know I called my car that. I forget exactly what I said, something like “Wanna take a ride in Jasmine with me?” or something. Whatever it was, it sounded like I wanted a threesome. Or at least that’s how she took it. Suffice to say, we never went out again.
Back in the 70s I had a yellow Vega – which performed exactly as you might imagine it would.
My friend and I nicknamed it “El Lemino.” We were gonna try to combine the nameplates of an El Camino and a LeMans to make it official, but we never got around to it.
Two of my cars have had names.
The first was a 1987 Chevy Corsica that was absolutely impossible to kill. She even ran with one spark plug broken for 2 weeks because that’s how long it took me to scrape the cash together to fix it (pull the head, guide the plug out by the threads, machine the head, etc.). She was a war horse. Consequently, she was named Bucephalus, after Alexander the Great’s horse.
The second car was a nice little sedan that rides like an elegant little dream. I named her ** Bernadette **, after a character in a Maupassant story.

Wanna go for a ride? It’s really speedy!
I’ve named every car I ever owned - and have also convinced all my friends to name their cars too. Since most of my prior modes of transportation fall under the “rolling heap of crap” classification, there has been a cast of thousands. A few stand out:
Jezebel, the purple mini-pickup with the broken seat spring that stabbed the driver in the ass on bumps;
Sharky, the non-descript gray sedan with the engine from an old cop car;
Barbarella, the Beetle that had, in place of the driver’s seat, a cheap folding chair glued in position;
Irving, the Ford Escort that came already equipped with a petrified burger under the passenger seat, presumably the last owner’s lost lunch.
I have recently, at long last, acquired a new car - a black Mustang convertible, predictably named Sally. She is most definitely a person and not a machine. I suspect she is having an affair with my boyfriend, and can’t decide which one of them to get rid of.
I name all my household appliances, too. Are you suggesting that this isn’t normal?
Hmm…
my mom had a yellow Chevy van named ‘Daisy’, a green wagon named ‘the Watermelon’, a Valiant named ‘Prince’ (of course), and has a Mercedes named, well, ‘Mercedes’.
My dad had a Saab named ‘@&$&(#’, and a little green Mazda named "Hornet’. He hasn’t named any others.
I had the ‘Blue Whale’, a '70 Gran Fury Coupe; 'Pony", a '74 Vega; 'The Baron", a '68 Candy-Apple red Camero; ‘Camel’, my long-legged Mazda truck; and ‘Marvin’, my green Saturn (hey, it’s green and comes from Saturn, what else would you name it?).
My wife drives ‘Elvis’, another Saturn. Hey, it’s blue and comes from Tennessee, what else would you name it?
I don’t own a car, but Mom’s were
Lurch
Wash and Squash (it had leaks and was small, like the old wringer washer still in the garage with the same nickname)
The Bronze Baby (her favorite)
Hopalong
Lemonade (it was a sickly yellow-green color)
I named my Jeep Enterprise.
My mom has a 1964 Ford Galaxie. Sometimes it’s called The Ford, and sometimes it’s called Andy (because the same model was used for the police cars on “The Andy Griffith Show”).
My dad has two Chevy Suburbans–a 1990 and a 1999. The '90 is known as Rustmobile because of a large patch of rust on the hood. I don’t think the '99 one has a name.
My 1993 Dodge Shadow has several names. Capacita Roja, Spanish for Red car is her more common name, and just *Capacita * for short. However, more recently it has been The Shadow, No. 2 Make-Out place in the City. My grandparents have had many cars in their time, al of which were females with the first letter of their name “A”. Thinks like Addison, Alli and Anne were all there. My computer goes by Hercules, but I do not remember how it got this name 
my 91 Nissan Stanza is dubbed ‘The Mighty Mouse.’ It is mousy in exterior (“metallic beige” I like to call it) but mighty in attitude. It has also save the day on several occaisions. In college I also lived with the owner of “Mission Control” a big ol’ Econoline with “mood light” buttons and a Betamax-enabled tv (!)
