Just a note of caution. Depending on where you live, it the car is not garaged, a cover can cause as much harm and leaving it uncovered.
Rust issues if it holds moisture in wet climates...or from my personal experience, dust/sand problems in the desert.
I bought an expensive cover for a Triumph TR4 project after I had it newly painted. A year later I found the cover had moved with the wind, and rubbed completely through the new Imron in a couple of places.
Just my 2 bits, YMMV.
