You can't go wrong with a Lexus! B) Just make sure you get all service, maintenance & warranty records on the vehicle........make sure everything is up to date, especially the maintenance. Miles on the car dosen't mean anything, as long as the vehicle was maintained & driven properly......if it was abused badly, you will know instantly. Good Luck! B)
In addition to the LS (considering the fuel prices going through the roof & seems like it will continue to do so), I would give serious consideration to the ES 300, or the GS 300. I'm personally a huge fan of a 6 cyl engine.......great for highway crusing, passing power, with a very good return on fuel economy in the city & highway & excellent longivity. I've personally never had the need for an 8 cyl vehicle & I am glad I choose the ES with the 3.0L V6. FWD helps up here in Canada, not to mention wet weather as well. ;)
