CarFax is absolutely the 1st thing, where I look at number of owners, service history, and accidents. Sorry, guess it was assumed that was where I got the info I listed.
Usually doing this remotely so then look at undercarriage, interior (seats, dash, controls), etc. If digital odometer, also ask about engine hours. Lastly, order an inspection once I agree with said price. Have had 3 vehicles make it to inspection, with 2 to fail, and 1 sold mid-inspection.
Been looking off and on for almost a year, now, across the country. Probably too picky but willing to spend $12K IF the vehicle has been maintained, minimal surface rust, and interior has not been beat to hell. I know this vehicles will go more but usually capping my mileage limits at 150, and typically more like 125.
