Need a bit of advice on a board choice.

Ok so I learned how to ride on a longboard. I'm not very experienced yet but I kind of have the very basics down. I'm going to buy a board of my own and I found one that I really like but I have a few questions. I would like to go as short as I can because I live in a dormatory and space is VERY limited. I also drive a small car that I can't fit a longboard in (I don't have a roof rack). Now I know that longboards are much easier to catch waves on but I think I might have found something that will work. The board is a 6'1", 20 1/2 inches wide, and 3 inches thick. It has a squashed tail and the nose is very wide. I'm 5'11" and weigh about 178lbs. I was hoping that the extra thickness and width could make up for some of the length. The board is also epoxy which I like because I know I'd ding the xxxxx out of a fiberglass board taking it in and out of my car. Is this board at all a good choice for me or should I keep looking?
Thanks
