How you doing morpheous! As an owner of a z4 then to an aero and the ex owner of a trad. I'd say go for the Aero. Although the trads look super cool, a touch impractical, especially if your coming from a car with a boot. Aeros have a fair bit of stroage inside, behind seats and a fair sized boot.
The newer the aero, the more watertight they become, Series 1 aero's are known to leak at the roof and the window seals. But if you can deal with a few wee puddles then there you go haha.
Age of car all depends on budget really, series 1 aero's start about 35 k right up to new ones at 70 k.
hope thats some help to you!
