About to pick up an 82 pick-up

Pun intended... :iceslolan

Anyways, I am about to buy an 82 Toyota pick-up with a 22R in it... Its been sitting for about a year, but the guy put gas in it, and a battery and it started right up, very little smoke at first, then none (normal for it sitting)... And hes asking $500 for it...

Anyways, my question is, I plan on using this is a pizza delivery truck, and to haul my 4 wheeler around in... So I need something dependable, good on gas, and cheap, but with a good amount of torque, and this truck seems too fit the bill... Am I correct? Anyone have numbers on average gas mileage on these? Also should something break on it, how hard are they to get parts for? As far as I can tell, these engines were made (in FI configuration anyways) up until 95, so they should still be pretty easy to get parts for right?

Thanks in advance...

Parts are plentiful, average is around 20 MPG.
Depending on where you are, give the frame a serious going over for rust.
The 80's Toyotas are notorious for it. The frame rusts from the inside out,so by the time you can see it it's bad. Use a small hammer to tap both sides of each side of the frame, especially anywhere it turns up/down from horizontal, above the rear wheels, and where the tank sits against the frame.
