Coupla things you may wanna consider...
Replace the plastic coolant tank with the stainless steel one that came with the car.
Good...
Driver side window rolls up too far, so replacing whatever limiter keeps it up to the right height, or replacing power windows with hand cranks.
I'm assuming you have electrics then... There should be a hand crank and an access hole so if the electric motor fails, you can crank it up and down. You'll need to pull the door panel and most likely break many more clips. You can find them online and through our vendors but at least one of us here used a commercial grade Velcro and said it worked great.
Repair the weather stripping on the left driver side where it leaks in the rain which I found out the hard way in this niño weather.
Even with NEW weather stripping they tend to leak... Many options here with aftermarket weather stripping.
Figure out if and where it's leaking oil.
Well... the best way is to clean up the engine and trans with a high pressure wash and them powder its bottom. Literally. Baby powder will cling and expose where the leaks are coming from.
Replace a few of the clips on the interior door panel.
See above...
Install the rear window brake light.
Well... Most 3rd Brake Lights mounted inside the rear window OBSCURES your rearward vision. Find a spoiler you like with one or another place to mount it. You'll kick yourself for mounting where the factory did. Obviously the guy that thought that up never drove the car. Installing some brighter LED Running and Stop Lights will help also. Directionals will require another blinker switch, but no biggie.
HTH.... Send Photos or else!
