I am considering buyinga 1998 ls400 with 105m miles. The car is in excellent condition one owner. It has not had the 90m service,and I am concerned about ruinning the engine. He wants 11,500 firm. How long do you think I could go before I have to have the timming belt and wp replaced. Is this a good deal. I plan on doing it but not right now. maybe in a couple of thousand miles. Do you think the car will last a few more thousand miles before I can have it serviced. Also roughly how much will this cost me. Any reliable independent dealers in the nw suburbs of chicago. Thanks Jimbo409
