the company i work for is getting a new 37g, they were deciding on a brand new one for 1.7 or going with one with 2000 hrs to save some dough, i have heard of a 37g2 not from reputable sources i might add, but they say the new 37g has a 6 cylinder in front, i hav read on cat the front will be c-11 that doesnt sound like a six. the g im running now we got brand new in 05, it has 22000 hrs on it, and 103000 miles on it, is there any major changes they hav made in the newer models, im pretty happy with the older ones, hopefully i will hav pics to share soon.
