Best (INDOOR ONLY) car cover?

Covercoft Custom Form-fit cover is the best indoor only cover I've seen/used personally. Came with my Viper and its perfect for keeping dust off the car. Purchased one for the 69 Charger and 04 Ram SRT and they both fit perfectly and look great.

I've had several CalCarCover out door covers and they all fail at the bottom elastic. Had one rip open at the stitching as well. To their credit they did send out new covers under the 5 year warrantee my cover came with but would rather not have to deal with that and just have a cover that stays together.
