I saw a 2007 CX7 for sale pretty cheap but it had 71K miles on it.
The guy said it was all highway miles and he has all the service receipts and that he used Full synthetic.
how much more life you guys think this engine has?
140,000 KM = 87,000 miles. I would expect that a well maintained turbo engine that is driven normally will last ~ 150,000 miles. I agree that the turbo or its components will be the trouble source or maybe the electrical system.
