That car is CLEAN. The engine bay looks showroom new... I honestly wouldnt let the 3.1 scare me off, great engines, great cars, good economy. If you ask me, the 3.1's have plenty of power to get the job done.
The price might be a tad bit high, but given how clean the car is, and the fact that you know its history, I might be inclined to pay the higher price tag.
