Are you looking for an outside or inside cover?
Moss sells nice covers, and I've always like the "Noah" covers for outside use. Just Google "Noah", you'll find a good vendor.
Lots of choices, of course, and a wild variation in pricing. You should be able to find a good quality outdoor cover for less than $150. Indoor covers are of course cheaper.
Points to remember:
1) choose one that "breathes": the fabric must allow air exchange, otherwise moisture will become trapped on the car's surface, promoting rust;
2) Choose a cover that's form-fitted for your car. Loose covers may flap in the breeze, possibly scratching paint/chrome.
Good luck, let us know . . .
