For those that wonder what's the overall physical difference between our E53 X's and the newer E70's then check out this very well presented piece of footage depicting just that. Dunno 'bout you guys but I reckon the front on shot of the E53 looks way better and meaner, I'm not just saying that because I've got one, just an observation and my honest opinion. Our brethren over the fence will have a different opinion and I respect that. I'm surprised actually how much longer the E70 is.
Bottom line, both X's are the nuts
