Wagons would be great for hauling and room for the dog. DSM not so good for a large dog.
Some wagons look pretty cool. Impala/Caprice SS wagons are nice. Some German fangled things are cool. Evo wagon though...not so much.
I'd still get it because of the AWD and the fact it's an Evo but not for looks. If you are going for an ugly wagon, Subaru covers that nicely. jk
