At 150,000 miles, and practically NO mechanical problems, this car is AMAZING! The engine runs like it's new. Of course, my penchant for religious maintenance might have something to do with that. It's comfortable, quiet, powerful and all-in-all pleasant to drive. Fuel economy is really good considering the vintage and engine size (3.0L V6) - 21 in town and as high as 28 on trips.
Handling, seating comfort, sound system (see below)
A little late for this - but the CD player and cassette player both died at around 90,000 mi. The radio still works but the dial lights don't. Neither Bose nor Nissan can (will) repair the system for less than $1,500 US.
