Corvette: Does anyone own a 'Zippered Bag' to store their Corvette in ?

I cant remember the exact name for them, but, they are a huge zippered
bag that you can drive your Vette onto , then zipper it up for winter .
I hear they run about $250 . Does anyone have one ? Does it work good ?
Where do u get them ?

Thanks, Dave

Thanks..ill look at the site.

I dont see why you cant sit in the car while its in the bag...although
ill bet its pretty dark in there ; sort of like the cave that Osama
resides in.
