Had to replace all 4 tires due to dry rot. Replaced Landau top and headliner soon after purchase about $185. Replaced all 4 disc pads on brakes. Put on dual exhaust when muffler went bad ($485). Seats and carpets are badly worn. Replaced dash and door panels from salvage yard due to cracking. Repaired Tilt on Steering column. Needs a/c compressor replaced and recharged. Needs minor body and major paint.
This is a really good car that sat in the sun for 5 years and wasn't taken care of. It was a one owner, custom built vehicle, and I am working on putting it back in it's original condition. It has only 88,000 original miles on it and is not by any means worn out, in fact, it is just barely broken in. It just needs some tender loving care, and a dose of spit and polish. The care runs like a top, gets up and goes and still gets 12-18 mpg so I don't complain too much. It cruises like a dream on the open road and levels out the bumps on the lesser roads.
12 to 18 miles to the gallon? I am lucky if I get 7. What kind of carburetor do you have on there? Mine is an aftermarket Carter 750, with a manual choke.
I have a 76 (great car) Thunderbird/460 with 54,000 on it. I have averaged 12-14 on rule country roads and 16-18 on the highway. One trip last summer hit all the lights right on rt.31 (speed limit 55 mph) going from Honesdale PA. to Hanover NJ. and when we filled up I check the mileage and still find it hard to swallow (even had my wife check it) 20+ MPG! The car is running the stock carb.
