The-cover-store.com Customer Service Issues

I own a [redacted] Plymouth Satellite Convertible with the original top, but it leaks around the edges near the windows. The car has been kept in a garage since the early 90s, with some exposure to weather prior to that. I purchased it in [redacted], and it will mostly be in Foristell, MO, for about six months before being housed in a shed upon completion. I plan to tow it with my diesel pickup on an open trailer at speeds of up to 80 MPH, as I sometimes take it to Medina, TX, where I winter without a garage. I am seeking a cover that can withstand various weather conditions, from cold and rain in Missouri to high humidity, temperature changes, heat, and UV exposure in Texas. I am also interested in covers with the longest warranties. Could you please provide recommendations for the top three covers, along with their prices? My car will be ready in mid-May.
