It was not a frame off job, but you couldn't tell by looking at the underside. We removed the complete interior and stored it carefully. Everything else was disassembled, cleaned, painted, plated, etc. Whatever was necessary. It was down to a rolling shell. All the trim, taillights and such are original to the car. We did need a front bumper though. That is how I got started into Gran Sports. Another story in itself.
Yes it is the 210 hp engine. The 4v and dual exhaust really wakes it up and the mileage is good too. If I recall correctly, my brother use to get about 20-21 mpg. When we traveled to shows, my brother always laughed at me because I could pass him and out run him with my GS, but I couldn't pass as many gas stations as he could.
The present owner lives in VA and has a lake home in MN where the car is kept. Seems he doesn't drive it as much as he thought he would. Didn't get the idea he needed to sell, just testing the waters I think.
