I bought mine used in 2002, have driven it 80,000 miles since. Build quality, handling, performance are great. Many small things have failed though, and at 170K miles it's on its third transmission (!). No other mechanical issues though. The engine is fantastic, still tight and strong and using no oil. I've driven the 4.2 AWD models as well, and I have to say I prefer the handling of my FWD 3.7 model. Weight is only 3600 lbs, about the same as a Subaru WRX. The 3.7 seems to have virtually disappeared from the roads now, though. At current rock-bottom prices these are a stupendous bargain.
Handling, performance, interior and exterior build quality, mechanical durability (with notable exception of the transmission)
