Not certain old cars are stupid. I suspect I have to change out an intercooler located on the back side of an engine of ours soon. Probably just about invisible until i remove a lot of stuff. The coolant pipes are all plastic.

I am at the age if the job looks too bad I will farm it out. Average depreciation on new cars around fifty percent over three years now. Gets cost per mile of usage right up there.

Now buying older cars with needs and farming out all the work. That can be a form of financial disaster. I have noticed some expensive parts on cars have come down somewhat with their age as well. The inter cooler I think I need was pretty expensive until aftermarket units came out eventually.
