Hmm I am struggling to find a choice between these for reasons aforementioned, as well as the following;
Porsche is boring, common and unoriginal and it astounds me people keep buying them (most owners would have no idea what a rx7/r34 gtr is but read in autocar its the car to have)
360 is impractical, too flash, too common (it is one of the common ferrari's, like f355's and f430s - baby ferrari = poor mans ferrari, not that i could afford one yet) and not unique enough to be a classic like a testarossa/288GTO etc. and a footballers/lottery winners car (not a good thing in my opinion)
Merc in my opinion has a image of a bit of an old man/middle aged owner (ok if you are 40+, no offence)
I have made some huge statements there and prepares for unslaught of comments. I am entitled to my opinions so there!
