Thanks for the strut update, my next job on my 2000 LS with 128K.
Some basic advice- Watch out for the 90K service, its a killer, water pump, belts, ect...
Tires- Have used Michelin MXV4, Bridgestone Turanza LS-V (discontinued) and just put on a set of the Yokohama ADVAN S4's, best tire yet, we'll see if they last.
Starter- Just went bad, classic one click symptoms. Lexus wants $1,450 to do it, My local toyota dealer wants $800.00, same parts. If your Toyota dealer is willing and able to work on your Lexus take it there, you'll save a lot of labor dollars and get the same parts. I was lucky, the service writer used to work at a Lexus dealer and the Tech is from Japan and Lexus factory trained, they love my car and like the fact that I take it there instead of the Lexus dealer.
Overall- One hell of a car, refined yet can still be a beast when called upon.
