Please post your location in your profile to help explain all that rust for a garaged car.
Expensive; grill $150 fender $300 , hub caps $300 , brake calipers $1K for 4, door seals $1200....if your engine needs rebuilt? It all adds up. when you pass $3K you have spent too much.
37K? probably 137K.
First just get engine running to see if it is worth doing anything to. If bad engine, then you have a parts car.
Have you tried all the jack points to see if rust there?
But hey if engine works, then start of rust removal and detail car, change all fluids, start driving.
I'm located in Burlington County, New Jersey.
The car was garaged for 30yrs except for the last. It did see the elements parked outside for one year.
The car has only 37k miles on it, not 137k. The interior is super clean. No rust at jack points, wheel wells, or door bottoms (some superficial rust under the car). the exhaust looks almost new. The door jambs are super clean. The doors seals and window seals are in great condition. I couldn't be more happy with the condition of the car in general.
The engine bay is scary looking, but a lot of that rust is on the surface. The worst area is the battery box. When I pop open the caps, everything looks wet and sexy. The oil level is good. The trans level is good. The coolant level is good. All fluids look good.
The brakes don't work and there is a cap missing from the fluid reservoir. I will try draining, new fluid, and a bleed to see what happens.
I feel confident that I can start the engine (following an old-engine prep and start procedure, of course). If it doesn't work out, then it's a parts car as you say.
Regardless, I'll be back in here asking questions often. I'm notoriously bad at tracking my progress, but I'll try to post my progress and curb that bad habit.
Keep the comments coming.
