you do realize that you are on an LS forum, right?
anyway, of course i'm going to vote LS... for some reason, the LS and GS/ES aren't THAT much different in prices... the ES actually keeps a pretty high value... now having said that, go for an LS... if you could cough up a few grand more you may be able to slot yourself into an 04+ LS... imho, a nice improvement upon the 01-03 ls430...
start here...
- autotrader
- cars.com
- ebay
- craigslist
- dealer auction (if you know a dealer that can take you)
good luck
