Dealership "repaired" my car twice and I still have a rough idle, gas smell and check engine light. They first replaced a cracked hose, was fine for a few weeks. Then replaced a gas valve. Repairs so far $900...I still have the problem. It's a 1998 w/ 164,000 miles and excellent maintenance-- needs new front brakes soon. I think it's time for a new (er) car as job 2 young kids, etc don't allow for luxurious afternoons spent at lexus dealership....not to mention it's hard to leave the dealership without promising first born....husband disagrees on time for new car... Looking for ideas on problem *or* ideas on a new(er) car. I think husband might defer to Car Talk expertise.
