A brown Datsun 260z (or it could have been a 280z) - haven’t seen one of those in ages. Still a very good looking car.
Spyder. Porsche makes a Spyder, Spyker is a different car (which would also merit an entry here). Stoopit autocorrect.
Saw what I think was a 70’s Plymouth Valiant, hard to say as all the badges were removed and I could practically smell the Bondo, although it was well masked by primer paint.
I also saw what I think was a Ford Model A hot rod, but it went by in a flash and I don’t know that era of cars very well.
This weekend, the most interesting car I saw was a Maserati Gran Turismo Sport, decked out in racing colors at a road course here in the Midwest.
Saw a PT Cruiser convertible, but the interesting bit was this - it had a nose bra! I didn’t think those were still around when the Cruiser entered production, and I don’t think I’ve seen one since the 80s. My old 1983 Porsche 944 had one in the hatchback when I bought it, but I never even attempted to put it on and didn’t include it when I sold the car.
I still see them once in a while, and I’m usually too shocked to even look at what kind of car is wearing it.
Driving around Palo Alto on a sunny afternoon, it was a target-rich environment. The bright sun brings out the best.
And I also saw some nice cars. 
3 come to mind now:
An early Ford Bronco, maybe 1972, very clean, turquoise color (that can’t be a stock color, right?)
A silver Pontiac Solstice - not common
A black Chevy Impala sedan, 1960, very sharp and clean and with that distinctive rear end. Beautiful.
Every morning when I look across the street, I see a Rolls Royce, perhaps 10 years old. I have lived here about 15 months now. I have never seen this car move!
Guess when you got one, even if it’s broken down, you just don’t give it up?
Two on the commute home tonight. First, a BMW i8 in white which looks like a melted i3. I’m sure it’s a heck of a performer but the looks do nothing for me. The second was a 1951 Ford F-series pickup with the funky grill. It wasn’t in showroom condition, but it looked well loved.
On the commute this morning I was passed by a white 2003 Pontiac Aztek. Honestly, it didn’t look as bad as I’d remembered. They toned down the worst of the body cladding in the last 3 years of the Aztek’s run. It’s more angular than modern crossovers but essentially the same shape.
Saw one right next to me at a red light on my commute home yesterday. Black on black. Targa 4S.
Odd that I’ve never noticed one before. The Porsche dealership is less than 3 miles down the road from where I live. Probably only took notice because I read your post earlier in the week.
I wonder how many Targa models Porsche sells.
Personally, i think that the Targa layout, with the wide B-pillar, breaks up the smooth lines of the 911 and makes for a less attractive car. The Targa option, with a hard roof insert, does make sense for people who want open-top motoring in the summer but who also want a solid roof for the winter, but if you live in a relatively warm climate (like here in Southern California) it seems to me that you’re better off either just sticking with the coupe (if you don’t care about open-top driving), or going the whole hog with the cabriolet. This is especially true if you don’t use the car as a daily driver, but reserve it for weekend road trips up the coast or whatever.
There was a time when the extra structural rigidity provided by the wide B-pillar and the targa roof made sense over a cabrio, but reviews that i’ve read of the 911 Cabriolet (and the Turbo Cabriolet) suggest that, for most drivers, there is barely any noticeable increase in body flex when driving the full convertible version of the 911.
A couple hours ago: A red Impala convertible with the top down. Late 60s I’m guessing.
With the top down, the “flattened” appearance of the body was even more noticeable. A long, wide, short car.
It was roadster day today, I guess. Started with an MG B, I think. I can’t really tell the difference between all those models. Then today on my bike ride there was a mid-80’s Fiat Graduate and finally a Aston Martin Vantage parked near my house. I couldn’t identify the car at first, had to look up the badge to figure out the car.
Targa sales have been miniscule for decades. Once Porsche released the cabrio back in 1983(!) (after the convertibles scare of the 70s) there’s been little reason to get one. Sales have fluctuated between a few hundred and a couple thousand in a good sales year. The models after the mid-90s have basically just been coupes with really big sunroofs.
The Graduate was an Alfa Romeo Spider 1600.
Yesterday at Bayfest in Somers Point, NJ I walked through a mini-carshow (about 2 dozen automobiles) which included a Chevy Apache panel van
American Motors Ambassador
Chevy Corvair (with factory option turbocharger!)
And a Maserati Merak

I’d never heard of a Graduate before. I’m guessing that name might be a reference to the movie, The Graduate. Dustin Hoffman’s character drove an Alfa Spider in the film.
My apologies, it was an Alfa Graduate. Brain fart on my part.
Actually, the most interesting car yesterday turned out to be a nondescript sedan with Wyoming license plates, which culminated my 2+ year version of the License Plate game done alphabetically.
