Is it a good idea to buy a truck that was previously used by a gas company?

The truck is a 2007 ford f150 with 233,000 miles. The asking price is $6,600 dollars. It looks like it's in excellent condition. I just don't want to put another $5,000 in repairs right after I get it.

How many times are you going to ask the question? Until someone says "yeah its a great deal! Buy it today"?
If your girlfriend wants to get engaged, get her a Ring instead of buying an old truck with a quarter of a million miles on it!

That's a lot of miles, have you had it checked out for any major mechanical issues?

Seems expensive for that many miles. I realize vehicles last a lot longer than they used to but 233,000 miles is a lot of them.

Leave it alone. Way too many hard miles if it was driven on the job.

Ask to see the service records (if possible) before you buy, and even then, have a mechanic do inspections of all systems

Lots of miles & probably "city" miles.

Get it checked before you buy
