Hello.(:
I have an SC400 with just over 167K miles and my father put about 5grand in and then I helped with the $2600 for the rebuilt tranny, so you need to make sure you know what you're getting into before you buy anything. There is alot to go wrong with any car, BUT if you love it, have to have it, and have the money, time and energy to put into it you should buy it! A car you love and enjoy driving is worth the extra work.(:
Have Fun with your future Lexus.
