Aren't these cars comparable to the size of a 3 rather than a 5?
I know someone with one of those newer wagons...v6 & auto tho.... Pretty cool, but when we park side by side (touring), it's a tough call which is a better looking car. E39 still looks good, but more traditional and business/understated. ATS wagon looks kinda spacey.
I think you should get it... the V
Being a SB Chevy, I would imagine there are lots of engine upgrade options too.
