I am looking at a 2014 luxury with 172k miles. As far as I can tell this the highest mileage 2014+ model for sale in the US. It is a one owner, southern truck, priced at 21,500. I currently have a 2007 gx470 and was looking to upgrade. Does this mileage concern you? Outside of the obvious things to look for (timing cover leak, valley leak, valve cover leaks, ect). I wasn't in the market for a 460 8 months ago, so I'm unsure as well if the price is inflated. Thoughts?
