Ok I am strongly thinking of buying a 2007 LS460 president , 166000 miles , but no history and a frozen touch screen , owner say car drives 100% , but I have been warned against it by fellow Lexus enthusiasts, I could get the car for under 4k and have 2 k to fix any mechanical issues, or buy a 450h with fsh for the same money, I just feel I would be missing out on the Ls , your thoughts people would be highly appreciated.
