The most fun I ever had in a car was driving a tricked out Nissan Skyline. It felt like it had at least 350 or more horses and I don't mind admitting that I didn't feel comfortable enough in my driving skills to let it 100% loose. Tempted, but an accident would have been a major loss due to the circumstances. See below.
Besides it's speed and the freakiness created by it being a right hand drive car, it was the "most" fun because it shouldn't even have been legally on the road as it just came off a container along with a couple of other cars my buddy was importing. The lift axle on the flatbed he was going to haul them with refused to raise so we decide to drive them back to his place rather than risk leaving them where they were (guaranteed stolen) so it was kind of a Cannonball Run experience. Stupid Yes, but it all worked out and my life is a bit richer for it.
