GTV,
Bongiorno!
Based upon the "last tag in the late 90s and straight, solid, complete, and filthy" say maybe ~$700-800. Some reason for this price -
-No idea what it looks like, exterior, interior, or engine, rust, glass, chrome, etc. Yes picture would be nice.
-No idea why it was parked? Tired of truck, brakes, won't pass inspection, would not start one day- endless possibilities with this one.
-Let them shoot you a counter offer of a little more and "feel good" about themselves.
We are probably both guessing it has NOT started for 15+ years so you should figure this into the cost. From all of my rebuilds- running or not - you should figure in $500-700 parts (no labor) to drive it around the block. This is if everything checks out and all you have to do is fix -
Brakes ~$150 for major rebuild of all hydraulics with kits and new brake shoe. Price will go up significantly if you need new Brake and Clutch master cylinders. And don't forget you will need about 3 bottle of brake fluid to flush/bleed the system
Tune-Up- ~$120 with all new parts, but good luck finding a distributor cap. $45 cap, $8 points, $4 for rotor, $6 condenser, $15 generic plug wires, $12 spark plugs. You can get the plugs, wires, and condenser from your parts store - all else is on eBay
Battery - ~$100 for a generic house brand.
Tires - ~$300 - $400 when its all said and done
Anti-Freeze - $25 or so.
Hoses/clamps - $55
Oh, and don't forget the tow truck fee if you have to go this route.
These are some initial consideration so your $700-$800 backyard find is now at $1400-1700 and all you have done is get it running. Now that the gremlins have had sunlight and food here are some other cost to consider -
Clutch replacement - ~$400 for all new parts, a little less if you rebuild the disc and pressure plate.
Gas tank boil and seal ~$175
Radiator tank, pressure test, and fix if necessary - ~$50-125
Generator bench test and fix (if possible) ~$10 up to $150
New starter ~$130
New battery cables - $25
And of course "big brother" will want his/her cut for taxes, tag, and insurance.
Some of the latest running 320s to sell on eBay have been around $1800-$2200, but all have major issues - missing bumpers, badges, wrong engine/transmission, rust, botched/no interior, flat bed/non-OE steel box, missing tail gate, bad glass, other issues.
I paid $356 for a '62 parts/disassembled 320 and $675 for a non-runner '64 that with a little work started right up. The 64 is now getting a new clutch (~$125) and engine rebuild (under $1200 with parts and labor).
Here are import numbers to the US- around 8300 from 1962 to mid-1965-
