Again like so much here this is MHO....ok?....A good cover takes care of issues like UV, dust, neighborhood cat prints (damn dog doesn't get loose enough to chase them things:lol: ...), and especially salt air (I'm almost on the water here) and of course prying eyes.....and as you said this car will spend about four months every winter in semi-storage. So for 1% of the total purchase price I have all weather protection inside and out. Just my thinking on the subject and your questions are EXACTLY what my wife asked....she thought about my answers and said go for it. I did. Thanks for letting me voice my thinking on this.
