Through a friend of a friend at a car dealer. An 88 90Q, 140K miles, running on all five, no leaks, and passes emissions, fully loaded ( whatever that means) car looks great. Car was a trade-in. Should last until my 82 TQC is reassembled. $500. Turned down an 85 4kq with 110k miles last year for $750 (still runing strong)
