I'm missing my old car - that didn't take long.
...plain and simple: I want another 1g, but this time AWD. However, a FWD will do if it's clean and without a history of problems (remember the car I just sold). The car can be in stock or heavily modded form - whatever you've got.
My major concern is that the engine be perfect - well maintained, low miles, perfect (or damn near) compression, etc. I'd prefer a working turbo as well

.
Otherwise, the tranny needs to be decent (not necessarily a fresh rebuild, but it ought to shift into all gears).
The clutch cannot slip, but can be stock.
The body needs to be decent - I don't want 20 dents like the last car I purchased (body work gets expensive). I'd like decent paint, but it's not required.
I'd prefer a good-great interior - again, not required, but a preference.
My final preference is that the seller not be full of sh*t. People do not like to be lied to when purchasing a vehicle, and I'm no exception. If you know there are things wrong with the car, I, too, would like to know.
