I own an 07 Camry XLE and am now very happy with it. It did have a few problems when it was new. These have been fixed when TSB's (technical service bulletins) came out for each of these problems. Just make sure the car has had the latest TSB reflash of the ECU that came out in May of 08 to eliminate hesitation and engine shudder at 35-45 MPH, and also the TSB to eliminate the dash rattles in cold weather. Ask the dealer if these were performed. If not, ask them to perform them before you take delivery of the car. The major problems with the 07 and 08 Camrys were problems with the new 6 speed automatic that was mated to the V6 engine. This will not be a problem with your 4 cyclinder, which has a different 5 speed automatic.
