The car park at my clay shooting club is a sea of utility 4x4's Range Rovers and estates. If there was any situation where arriving in a Supra was going to make me feel self conscious about my car, that would be it. Not a bit of it...I'm into Supras because I love the car, the shape, the engineering, the reliability etc. I pick clients up from airports in it, I've parked it outside top flight hotels with pride, never felt anything other than buzzed when I drive it.
What others may think of my choice of car is up to them. Be yourself, and if you want a Supra, bloody well go out and buy one.
