Jordan - is this the van your looking at?

If so, the body looks pretty lumpy.
While heater and cruise systems are generally easily addressed, anything and everything can get expensive, depending on whats at fault.
AC repairs can run the gamut but the general rule of thumb (for ANY vehicle) is to plan on a couple grand (min) to resurrect a system that hasn't been operational for some time.
If the AC blows but isn't cold, I would NOT assume it "just needs a recharge". (Have seen that line quoted in ads so many times it is no longer funny.)
Seriously, if that was ALL it needed, don't ya think the seller would charge the system, so that he could command a higher price?
If I were in your position I wouldn't want to spend 25% of my available capital on shipping charges.
I would also consider $3300 for a 2wd to be top dollar and I would also expect it to be near perfect in all respects, for that price.
(what a seller has put into repairs has NO bearing on what the vehicle's actual worth is, that is determined by market forces alone)
Having a rebuilt engine does not ADD value to a vehicle, said another way - a $3000 vehicle is still only worth $3000, even with the rebuilt motor.

PS - If I am reading those invoices correctly, it looks like they overhauled the top end and did some cooling system repairs in July.
Then in September they installed a "Crate" engine.
Sounds like they're tired of tossing money at the thing and want it to be on someone else's dime from now on??
