My dream car is the one that looks good, handles well, doesn't use any gas, and is easy on insurance. It would have to be a convertible also. So far, I've never seen a car that meets that criteria, so I don't know what my dream car is.
1970-1974 Plymouth Barracuda meets: looks good, handles well, and is convertible. Misses on insurance and gas.
1989-1994 Chrysler Lebaron GTC convertible: convertible, easy on gas, easy on insurance, looks decent, but doesn't handle too well. (Although not bad...)
You get the idea....
I've had two favorite cars though. A nearly perfect 1975 Plymouth Duster and a 1986 Plymouth Reliant. The Duster looked good, sucked gas, was decent on insurance, and handled pretty well. With wheels and tires, it looked good! I owned this car at the same time that I owned my 1986 Plymouth Reliant wagon. I met my wife while owning both of these cars.
Every car that I've own since then has just plain sucked. Mainly uncomfortable and not fun.
EDIT: It's not the car, it's what you can do in the car?? Well, sort of I guess. I did do something in the Duster with my girlfriend at the time. Never did anything in the Reliant that I remember. My wife didn't want me to sell the Duster, and kept reminding me of that thing that we did in it. But I sold it anyway!
