Will the 79 to 86gts increase in value down the road? Is it better to keep it as stock as you can? I have a 86gt ,body is in great shape, needs paint soon, should i stick with the original color canyon red. I,ve been keeping the original parts, when I do a performance upgrade. There aren,t as many gts up here in Canada. and the ones they shipped up here were called Canadian export cobra gts. Does that add any value to them? Came with Km speedoes etc. Any advice would be appreciated.
