The mileage is in line with the age of it, but I would not buy it and not expect it to be a project vehicle.
If you can get it with a WRITTEN 3 day $ return, then take it to a front end shop and verify complete condition. Do a compression test, and send in an oil sample. Pull the diff covers, just catch the oil so your not buying all new oil for a truk you may give back.
Tow something heavy with it to see how it does.
I ALWAYS take any vehicle to a smog shop and pay the $20 pass or fail. (Getting my smog will be required anyways) while on the test drive. I do it at the end once I decided to buy it as a last check. If it fails, I lost $20, not thousands.
Since it is a car lot sale, they are required to have certian things pass inpection- brake pad thickness, etc. usually it's around 20 items-find out from your dmv, and hold them to it. That is the only advantage to buying used from a lot- you will pay more but can hold them accountable. New pads, new windshield wipers, bushings, etc can add up to $ saved on your end. I had a friend that bought a $3000 truck that the car lot had to put in around $2,800 to bring it up to snuff. It's worth the time to learn your states rules.
