New to F-Series Forum. Just bought myself a 1987 F-150 XLT! What in your opinions do you all think its worth from a private party, before I say how much I paid?

-Standard Cab
-Long Box
-4 x 4
-4-Speed Manual w/ new clutch
-5.0L V8
-Running boards, hitch
-Brand new tires
-Interior is 100% mint! Blue in Color
-Fiberglass Cap, painted to match
-222,000 miles(All highway and accounted for; He was the original owner and has a book of every single oil, air filter, tire, battery, brake, etc. change ever done by date and mileage with receipts to prove it!)
-Runs and idles good, shifts fine
-Paint is 2-Tone, Silver-Blue redone a few years ago now and is starting to rust out in the lower doors and bumpers. Otherwise mint - still glossy and smooth!

-The problems: Needs new driver side exhaust manifold gasket, front window leaks a bit on top(probably the weather stripping, nothing a little silicone wont fix), gas tank has small leak on the top so tank cannot be filled completely to top(How much will a new tank cost? Or should I just use some JB Weld?)

Well beings I'm a cheap-ass I wouldn't have given no more than $1000. Plus it has a 302 5.0 which are a dime a dozen and it' got 222,000 highway are not that's alot! And about the fuel tank, Jb weld it. Or go to any auto store and pick up the JB weld putty for $2.00-$3.00 and apply that to the leak. The tank is held up by 2 bands and bolts, very easy to drop out for repairs. I just did mine, and make sure you put the rubber/felt back in place on the bands or they will rub hole's into tank.
