Not sure how it happened. Just picked the car up this past weed end. I saw it when we were looking over it and used it as leverage when negotiating a price. We bought it cheap enough to replace the top but I thought I would get some opinions before just shelling out. I tried to look it over as it folds up but everything looks clear and it operates smooth. I think the bulge in the frame is normal, I believe it is just the angle but I will certainly look into it. Thanks!!
