my 97 olds 88, just rolled over 100k, second owner, 41 k when I purchased it, originally sold new in Sarasota Florida, and had never left Florida until 2015, it was kept in a car port before I got it, after exposure to Florida sun, all the paint fell off and was mostly primer, My brother and I repainted it in summer 2015, took us 2 weeks, sanding, removing all panels, hood, trunk lid, bumper covers, mirrors, header panel ..tail lights/headlights...trim..etc... it was alot of work!

it'* hold up well now in Ohio, made it through 2 winters, still no rust anywhere

things I have replaced
Radiator
Heater core
Head liner
belts/hoses/antifreeze
coil packs
belt tensioner assy
oil sensor ( leaking)
back motor mnt
upper/lower intake gaskets (lower was leaking)
headlight assys
brakes/drums/pads/calipers/wheel cylinders
struts
ball joint, rear/pass side
wires/plugs
just changed transmission filter/fluid
fuel regulator
removed factory radio, installed double din updated cd/radio with bluethooth, so no holding a phone when talking, new speakers

only big issue was when I purchased it, the car had severe shake above 50mph, hundreds of dollars later, nobody could figure it out, balance, tires, etc...I figured it out.. a rear brake drum was not balanced, just replaced them, no more shakes

Sounds like you did a lot of work to it, looks good!
And it should last you for a long time the way you take care of it!

Looks great! Do you do windows?

My Grand Prix could use a detailing too, do you take appointments?

^ ha ha Ya x 2 PA needs detailing!
Looks new with that paint work! Good Job! Engine bay looks great too!

Sometime I will hit PA with Clay bar & wax..
Last week, power washed all the window seals, trunk gutter, was nasty!
