Great value
 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!
