1988 Pontiac Grand Prix SE w/Getrag 282 5-Speed

[amiko]

Greetings forum members! New member, so thought I'd take a moment to introduce myself. Last Spring (2025) I acquired a relatively pristine (54k miles) 88 Pontiac GP SE. I hadn't even known they made these with a 5-speed, so I hadn't explicitly been looking, yet lo and behold here we are.

I've got it on good authority I'm only the second owner. It started life in central NY but spent the last 10 years parked in a sweltering hot garage in central Florida. It was never ever even registered in FL.

So it's got some internal heat damage, which I've been repairing. The door upholstery glue had given up years ago. The stereo was a mess, but I replaced all of the capacitors on the amplifier boards and even plumbed in a bluetooth module to the cassette inputs.

I'm not much of an auto mechanic myself, I do cybersecurity for a living, but I don't mind getting my hands dirty on projects like this.

On the serious mechanical side, I've had it at a local "rural mechanic" who's did a flush on all of the fluids, changed out the master/slave cylinders, and replaced the brakes.

I seem to have dodged the bullet of any serious rust or corrosion, but I know these are prone to rotting out their rear strut towers so I plan on installing a strut tower brace and blast the insides with as much cavity wax as they'll take.

Any other "gotchas" tips, tricks, or suggestions for keeping something like this roadworthy? Google's AI guestimates, based on statistical analysis of scrap rates versus production numbers, there may only be 15-25 "roadworthy" versions of this model, trim, and transmission combinations left anywhere

I didn't buy this planning on a super rare preservation "duty" yet here I am...any suggestions would be greatly appreciated. Don't worry, despite living in the salt-belt, I don't plan on driving it in winter for that reason...I do hope to drive it during the warmer months though!

An 88 GP was my very first car when I turned 16, so I'd always been looking for a decent one, "just for fun". I never planned on ending up with a bigfoot-riding-a-unicorn of rarity...something I'm not all together happy about...yet here we are!
