Z3M Not bad but expensive to keep on the road... quite a few have seal issues (unless its a coupe!)
Z4 nice but sloppy steering, need to go 3.0 or above
Boxter shocking driving position
Elise not a daily driver but would have one any day!
VX220 see above but I dont really like the shape
TT older ones starting to have issues with seals ets (something with german cars?)
S2000 as others have said
Zed has its problems, but agree with all above!
