It is quite a list. The thing to remember is this. There is about a 90% chance that any used car (especially any sports car) that you buy is going to need somewhere around 10-15% of the purchase price in work right off the bat to get it to where you want it.
No PPI or other work prior to purchase can fix this. Spending time driving a car regularly is going to enlighten you to all kinds of things that you want to fix.
I bought a "good" car and have already done:
Wheel balance
new top
new cupholders
sway bar endlinks front and rear
new floormats
lots of paint chip work
new wheel centercaps
replacement of CD holder with cubby
new front hood solenoid
tons of new undertray bits
one spare key made
new sunvisor mirror assembly
replace broken ashtray with storage bin
I've still got a couple of rattles floating around in the car which are making me nuts. I'd love to replace all of the rear windscreen bits which are a large part of the rattling. New rear tires need to come sooner rather than later. Also need to do rear trailing arms.
I've noticed that some prior owner tried to "fix" the engine cover and bose speaker carpeting that faded by stapling on some ghetto black interior carpeting. Some day I'll want to replace that as well.
It's just the way it goes sadly. The only good thing about this is that as I repair each thing I know it's where I want it to be. Even the "perfect" car is going to run up a list of crap to deal with.
So you have two options. Fight it out with this car if you truly like everything about the car. Year, model, options, colors. These are things that money can't fix. Sell it and move on to a Honda-ish vehicle you don't care about.
