I got myself a Covercraft Dustop from these guys. There was a promotion when I ordered it so it cost me a bunch less that they show on the site. You'll likely be able to do the same.
Somewhere there is a chart that compares all the features of all of their covers. Just search the site.
The one I got was 'Best' in just about all the categories. My Z is inside a parkade open to outside air but completely undercover. My only issue is dust accumulation so I had dust protection at the top of my list, along with the best paint protection they offered. The cover is custom made to fit your car and fits awesome. I went with mirror pockets (an option) They help to get it on IMO.
I just can't stress how well it fits....it leaves about the bottom 3" of the wheels exposed. Fits like a glove.
I had a decent cable lock from another cover I had so I used that instead of ordering the optional cable lock setup for this one. I threw away the cord that came with it and put a better lock on the cable I had. If you don't need to lock it to keep some jerk honest, no worries. It fits so well the cable/lock setup insn't necessary to 'hold' it on. I figure it just might come off in a hurricane if it was parked outside though.
