I purhcased the OEM one with the car, then added the high wing later. Its stretchy fits great, and when you lock it and have the mirrors fold in, with the cover on, no issues. One thing to note, I purchased the one with the "access panels" which has zippers to enter the frunk and rear while the cover is on. In hindsight, I would have preferred the one without the access panels as you have to be very careful when you lay it on top of the c8 and unfold it, that none of the zippers touch the paint. My old one on another car didnt have them and if I was to buy again, would skip the access panels version.
