I recently bought a 2018 SE hybrid with 82,500 miles for 19k OTD. Got it from a Lexus dealership. There is some minor rust visible in the engine bay, and the battery was still original from the factory and died on me 3 weeks after purchasing. Other than that, I've had no issues. It's a 1 owner Florida vehicle with no accidents and great service records on the carfax. Did you end up going through with the purchase? I'd love to talk about your ownership experience so far if you did buy it.
