Just picked this car up about a month ago. It is almost in mint condition. The only flaw is the vinyl top that needs replacement.
Have so far replaced:
1. Front main oil seal
2. Lower coolant line
3. Some brake lines
4. Water Pump
5. Wheel Cylinder
6. Front Engine Mount

..and a few other things.

Here it is after i mounted up the Classic Customs grille.

Interior is mint.

Some plans i have for it:

Bumper kit
Belts & Buckles
Maybe discs & vogues
Pop trunk w/ neon

Probally go with a MA audio system, and this time around im gonna do 2 chandeliers, for those who dont know what im sayin, check out my black Buick:
