lol @ rayder1 ... he's got the same practical mindset I've got, giving a rather realistic possibility instead of a strict fantasy ...
Actually, the query was worded "If you could have any ONE car!!!!!!!" (emphasis mine) ... I might well have responded with something more exotic had I not been practical enough to realize that a Z3, a 'vette,
a Ferrari, Mazzeratti or a restored beauty from the past such as a HemiCuda is quite restrictive if it is the ONLY vehicle one owns ... actually, I worked for a Chrysler dealership from 69-71 and HAD a Cuda demo assigned to me ... I had 3 small kids at the time who used to stand on the floor in the back seat so they could see out and sing the song from Speed Racer as they urged me to drive "faster!!!" ... lol ... so, I know from experience how impractical a "dream car" can be if it's your only vehicle.
Had the question been worded to ask what dream vehicle you might add to an existing fleet, I, like Rayder, would've been a little less practical ... but Rayder, I'm with you pal ... I've test-driven the Lexus and know what a sweet ride it is ... so, in my case, the answer to the question is a vehicle I am quite likely to actually own, not just dream about.
