Hi, I'm in the market for a dependable car. I'm looking at a 2002 ES 300 with 67K miles for $7.5K. I have googled for info and come to you all for first hand knowledge. I am wondering about the cost of maintenance for this car. I have read that they will last for ever if taken care of. How much should I expect to pay for routine maintenance. Does the work have to be done at a Lexus of Toyota dealership?
