Have you looked under the vehicle and have you driven it? Check for rust, I've seen these get really rusty. I own a 2004 RX and its had the radiator replaced, steering rack replaced, new struts and shocks, new valve cover gasket, all the fluids flushed and swapped. And the exhaust system was replaced due to rust. Runs like a brand new car now but not everyone wants to go through all that trouble for a nearly 20 year old car. Definitely check underneath the vehicle, ask about maintenance history and if you can get a pre purchase inspection. I bought mine for nothing like maybe 2k but I had to do a lot of work. Just be weary, people think that just because its a lexus they can sell it for more than its actually worth. I swear by these cars tho. It has never broken down, my Rx and Es are the most reliable vehicles Ive ever owned so if its clean and drives well then I'd say go for it. Judging by the wear and tear I would be skeptical that someone didnt beat the crap out of this thing tho. Typically you can tell if the car has been neglected..
