It would be so easy to do the old ZR=25, ZS=45 & ZT=75 joke at this point, but seriously there's nothing wrong with driving a nice car that might be considered a "mature" choice.
That ZT in the pics above is a really good example - what a handsome and well equipped car!
It can be a right shame to see old giffers getting out of Ferraris and Aston Martins, because only they can afford to run and insure them after a lifetime of saving.
Having said that, if you see someone really young driving similar, it can make you wonder if they're:
a) a footballer,
b) just out in "Daddy's car",
c) selling something naughty!
At least nobody's going to accuse you of being a drug dealer if you have a ZT (unless you black out all the windows, slam it and put 20" chrome alloys on it)!
