What a brilliant thread. Ive been watching for sometime. I should have done one like this for my sc430. I bought it in October of last year with 180000 miles on it, the previous owner kept driving it to Austria and back as he liked skiing. It was full of scratches etc. All I got was a receipt from him from Halfords that the water pump and cambelt ( but because it was Halfords I dont think the work has been done). I didnt get no service history with it, got all the manuals but apart from service book, I checked at Lexus dealers and they dont have a record of it, So first thing I did a week later was change oil and filter, parts from Toyota, then ball joints etc, then got car the car fully resprayed, I paid slightly more than you did as I went for Porsche lapis Blue pearl colour, then last week gave it a full service, oil, oil filter, air filter and sparkplugs all from Toyota at trade price, and wheel alignment and thats it.
But ive always always wanted an Ls460 and maybe one day Ill have one. Just need to save up abit. But I love you ls460. Nice colour too.
