With a van to tow with, the 7' wide is an ideal package (I tow with an SUV) as the narrower width over the standard 8'6 wide will tuck into the shadow of the tow vehicle and your mirrors will work nicely. It will save a lot of fuel on towing as well.
On length, the short answer is this: within REASON, a few extra feet makes little to no difference on purchase price, mpg, or towing handling but all the difference in the world inside the trailer.
I use a custom ordered 7'x18' enclosed trailer for my 5.5' x 14' car and widthwise it's great, but lengthwise it is tight with a full row of shelves across the front. I think for a "minimalist" setup with a slightly smaller car like yours, an "off the shelf" 7x16 enclosed trailer is easy to find, reasonably priced, and will work perfectly.
