Im with keithh. but if you dont have that, i just got one from wal mart for an SUV. it hangs over down to the ground but it covers the car and doesnt scratch the paint. the mirrors placement doesnt match up but i dont care. just tie the bottom of the cover to the bumpers and your good to go. easy to wash also.
I also have the California Car Cover cover. I got the Noah. I wish that I have ordered it about 6-8 in. longer to cover more of the wheels. It's pretty good though for outside protection especially here in the East coast. Cost me more than $200 and it took about 2-3 weeks for them to make it.
