Some I have thought about learning more about:
1. PT Cruiser GT Convertible If you can overlook the styling they're great cars - I just think the ragtop version of the PT looks a bit odd. I love my PT Turbo although it's not a convertible, and I've had ZERO problems in 5 years of ownership since new. Runs low 14s in the 1/4 mile with the Stage 1 upgrade too.
2. 90s BMW 3 series This would be my first choice, hands down. Great car all around.
3. First gen Camry Solara In my opinion, one of the ugliest cars on the road today, plus I just basically hate Toyotas
4. 93 - 02 Mustang GT I can't decide if I like these or not. Every now and then I come across one that catches my eye, but they just pale compared to the '05-'09 cars. Still, it meets your criteria and would be high on this list in my mind. The fact that it's one of only two RWD cars on this list is a major point for me.
5. VW New Beetle Turbo Yikes! Really? You'd drive one of these? I can't get past the styling even after a case of beer and a fifth of vodka. If you can't drink something/someone pretty, then it must be fatally ugly
6. Early 2000s Mitsubishi Eclipse V6, though I always liked the older turbo ones better. Nice little ride, no doubt about it, but do you want a car that merely has a back seat, or one that has a useable back seat? There is a huge difference, and the back seat in these is nothing more than an upholstered parcel shelf with seat belts.


Of course, all the above are merely my opinions and certainly not intended to offend anyone.
