07 or newer Alpine White/Sepang Bronze/Carbon trim M coupe with BMW Assist, Navigation, and most importantly a small turbo pushing single digits for boost. Its got everything I want: 2 seater, hatch in the back to hold your crap, looks good, has an exuberant amount of space to work in the engine bay, a regular Z4 with the top down is one of the stiffest cars I've ever driven so I cant imagine how nice an M coupe would be, parts are readily obtainable for obvious reasons, etc.

They truely built this car for the enthusiast since they dont have runflat tires, ONLY comes in 6-speed manual form, Xenon HIDs come standard, hydrolic power steering (why they didnt keep electric is beyond me though) blah blah blah

Other than that, either a MkIII or MkIV Supra with around 450RWHP, manual, A/C, excellent quality supporting mods, etc.
