Take it from me, if you dont own a 2 or 3 yearold lexus, chances are, they dont really care what you think, even thought, older Lexus' bring in more money due to higher out of warrenty repairs, but your just different to them if you dont wear a 20K watch, or wear expensive clothing. Sometimes i have to actually "dress up" to get decent, honost service, and my car isnt really that old (98 LS). It's sad, but true. and if you look very young, forget about ittttttttt.
Dont believe me? Ask all the 02-04 owners (esp SC guys) about thier experiance, and compare the responses with owners of 90-94 LS/ES/SC owners.
