For inside, dust prevention, I took the cheap way. Two old soft queen size sheets sewn together.
Easy on-off, won't scratch, covers all the car fine, soft.
I have interior covers from both CoverKing and CoverCraft. Both are equally fantastic! CoverKing calls their plush indoor cover the "Satin Stretch" and CoverCraft calls theirs "Form Fit." It's been a handful of years since I bought them, but one company had a cobra snake emblem you could add to the nose and the other had a striped cover option (for my Shelby). Both cover offerings are super plush and work great for indoor use. I used them before building a separate garage, but now I just leave the cars uncovered.
I would buy whichever one offered the better deal.
Coverking is every bit as good as California car cover only cheaper !!! Sell all kinds of custom fit covers for inside and out !! Been using them for decades ! No complaint from me
OP, don't know if you found one yet but I was comparing coverking and covercraft, both around $399. I did a search for coupon code and ran across AutoAnything and they had Coverking Satin Stretch for $349, plus 20% off, so it was $279. I couldn't resist at that price. Only difference I saw besides Coverking site itself for $399 was I couldn't do any stripe options and warranty is one year vs four. Being it is just indoor, I wouldn't think extra years would be needed.
