Re: the peeling/faded paint Green 80 above with cracked dash pad and torn leather seats, carpet, and steering wheel leather:
Rough numbers IME:
Cost to paint and replace moldings, minimum $6-8,000 (top shelf job double that),
Cost to redo interior minimum $3500 (steering wheel, carpet, front seats, console leather)
Cost to replace cracked dash pad: $2500 parts and labor
Base-lining (fixing all the leaks and neglected maintenance): $3000-5000 to start
Add $7000 if head gasket is bad, double that if engine needs replacing/rebuilding
Tires: $1200 minimum
Windshield: OEM glass is NLA so aftermarket only
Total estimate: ~$15,000-20,000 minimum to get it into a condition where the princess would drive it (and let you park it in the driveway)
