I bet the M3 is a great car, just irrelevant to me. I aint spending $50K+ on a car. Any car. Hand me a blank check, and while I might drop stupid money on something like a 427 Cobra or a Lambo Miura, or maybe even something goofy like a suicide lincoln, I'm still not going to drop $50K+ on a new sedan. I won't fault your 5 stars, and I won't fault someone else for buying one, though I might roll my eyes whethey aren't looking at the thought of how much more car they could have bought for less.
OTOH, I recognize that since I'm not a potential buyer of the car, that my opinion is irrelevant, and I'm OK with that too.
As for what is my 5 star car, value is a part of the equation, so they are all used. While the new M3 might not get 5 from me now, it very well could in a few years. Other 5 star cars:
05+ Mustang - For getting the modern muscle car right.
Original Subaru 2.5RS - Right car at the right time for Subaru Integra Type R - The ultimate FWD machine, even 10 years after it's introduction
JK Jeep Wrangler - In the face of watered down competition, Jeep releases the best wrangler yet, and makes it family friendly for the first time.
