Cars your afraid of owning

[Acidburn]

After chatting with a mate tonight are there any cars you are afraid of owning for whatever reason, i.e. expensive engine rebuilds, bad handling, shell stress cracking etc.

There are a few i'd like but think they'd be a wallet buster

cosworth - unless you get a good low milage or one thats freshly rebuilt, how long before another rebuilds required?

intergrale - i've heard stories of the shell stress cracking. Also rust and any wiring issues

subaru - rebuild around 100k and gearboxes made of chocolate

audi rs6 - suspension, gearbox, petrol costs

porsche/supra - some of the more tail happy capri handling versions.
