I bought a 2008 400H almost 2 years ago as a certified used with almost 40,000 miles. It is all wheel drive and other than the main hybrid battery failing(under warranty) we have had zero issues with it and now have 64,000 miles. Depending on who drives, me or my wife, the mileage varies, I get better than her average around town/highway about 27-28. I do believe the tires that are on the car are what is keeping me from any higher averages. When time comes for replacement tires I will investigate what will work for us. We live in southern Arizona, so no snow to deal with so cannot help with that question. The seats are very comfortable for long trips and we like sitting higher than most cars allow you to sit. We see many of these RX models in and around Az and I'm pretty sure when we hit 80,000 miles i will trade/sell this one and move up to a newer one.
