2003 Nissan Altima 3.5 SE 4dr Sedan (3.5L 6cyl 5M)
I bought mine used off of a corporate lease w/ 40k mi. Just clicked over 100k. The brake pads were replaced at ~65k, and it now needs new struts. If you're looking used, look for the 3.5L V6 and the 17" factory wheels. The 2.5L has good performance and fuel economy, but the 3.5 is a much better design and build quality. Fuel mileage is only 1-2mpg down from the 4 cyl. 17" wheels have larger brake pads that handle heat better and don't warp. Only downside is pricey tires. Still looks sharp and rides great, and I can tow a small trailer (PWC, and a flatbed for motorcycles/ Home Depot trips) with no problems. Much better than the Accord I traded in in every way... haven't looked back!
Acceleration, smooth transmission, available class 2 trailer hitch that bolts to the frame. Nice stereo. Still looks good. Roomy and comfortable. Great gas mileage for as big as it is. Real tilt steering, with friction lock telescoping.
Slow opening sunroof. Rubber cupholder insert has to go. Poor placement on seat heater controls, and overall cheap plastic interior. Not a lot of aftermarket support for upgrades.
