I did some shows with lone star buick back in '91- '92. We had an 86 in 86 and when Buick said 87 was the last year my dad got one and said when I finished college it was mine. We were in Colorado at the time. The car came here in '91 and went into storage around '95 because I had no other place to keep it. I got married and 4 kids later its time to teach the boys a thing or 2 about the car. I just sold my 70 Challenger and I also have a 64 malibu ss that needs restoring, my father-in-law was the original owner and it's stock except for 2 snow tires and 1 battery cable. I will start using my 86 century GS as my daily driver next month. I also have a '70 Wilcat 455 that I will be selling, I just need to get the title changed from Florida to Texas.
As for mods on the GN--None except for plug wires, those oem ones were no good, and an anti theft fuel cut off system. The original tires are still on the car.
