Your 2007 with 35k is hardly old. It's barely broken in. As a friend told me when I bought mine, take good care of it and it will take good care of you. There are quite a few 100k+ Z4s on here and I'm sure they will chime in soon.

I think elwesso nailed it though. If you've found a car that stirs you, why give it up out of fear or concern over what may or may not happen. Maintenance and a repair here and there are way less than a payment. If you're really worried, get a AAA membership that will keep you out of the weeds in the unlikely event something happens.
