I also have a tough time to find SR5 4x4 (S. California). there is no a lot of choices, so i have to pay almost a full price for mine. I got mine in February 2010 and the VIN Start with JTE**********9000. Built in Japan in 12-09. Consumer Report rated it below average for handling, turn to turn and accessible, but rate above average for crashed tests. IMO this Vehicle is an OK but nothing is out standing.
Are you really willing to pay almost full price for something your consider "OK but nothing is outstanding"? If you're not liking the handling of the SR5, have you tried the Limited?
