I was in that boat myself... did i want to go 98GS3 for 33k or brand new IS for 35k. I am glad i went IS... A mechanic at the dealer told me that they seen a lot of GS's come in for service and they look BEAT! seems to get a lot of abuse. HE siad it is very hard to find a really good close to certified GS out there. he said he would even second guess the Lexus certified GS's. He finally made a good point... why not be satisfied for spending 35k ob brand new, than worrying about what may go wrong at 33k.
