@park .... wait WHAT!? haha that's too funny I was on Maxima.org as well... for a good 7 years now and I just posted my farewell post .. lol that's crazy.
i will post pics like I promised and as far as gas mileage I've been getting anywhere from 24-28 mixed driving but over 30 on the highway - I'm not sure how much over 30 I haven't done much over 500 miles yet. but this is amazing to me - being that my maxima wasn't reaching much over 20 even highway and the x3 is pretty much in the same boat. damn, I LOVE my lil diesel
