Tough sticking to just 5, I'm excluding the obvious vote(s) for current LX's
Audi S8

My uncle is the orginal owner of a non-SD. He ordered an SD with Auto, Calif wouldn't let the SD in so he changed to std 455 w/ 4 sp.
1968 Charger 440 Magnum. Green, Black Vinyl top.
Mom's car when I was 2, and the reason I'm addicted to torque. Spent most of my childhood pinned to the seat my mom raced around the back roads of Arkansas.
87 Buick Grand National GNX
Having worked on imports and eaten a ton of sand out at Palmdale years before anyone thought a honda could be fast or furious, I loved the GNX (all turbo T-types) because it finally opened up some peoples eyes that something besides a 400 cid V8 could kick some ass down the track. The syclone and typhoon get honorable mention...
McLaren F1
There are a lot of "super cars" that could fit here. I always dug the F1 due to the center seat for the driver. Being borderline OCD being totally symetrical appealled to me and logically speaking, if you're building a car from scratch why not put the driver in the middle. I also liked the McLaren attitude. When people asked them how fast the car was, 0-60, top speed, 1/4 mile, they usually replied with ballpark numbers. "Over 200 mph"... "about 3 seconds"... they built the car to be the ultimate drivers car and whatever performance it happened to have was secondary.
