You can't fight rust and degrading rubber. That's whats killing these old cars. My parents just walked away from a 14 year old Subaru. Headgasket was shot, fuel lines and brake lines rusted and shot, whole laundry list of other rusted and shot components like suspension, dash lit up like a chrismas tree, total bill was going to look like $15k for a car that wasn't worth $9k even before all this went down. A car is a wear item and eventually needs replacing unless you have years worth of knowhow and own expensive equipment like a lift and sometimes specialized tools for your vehicle.
