well, waddya need from the cover?
indoor?
outdoor?
theres a coupla good ones to pick from.
i have a covercraft on a mustang that sits outdoors all the time, and it does a great job, and it rains here a bunch.
i bought a cheapo budge to cover my chally indoors, and in the body shop, all the while being subjected to dust, and overspray, it seems to be awesome.
both were under 100 bucks.
like i said, it all boils down to your personal needs.
hope this helped.
