I ran a Cat 287C for a few minutes today. I subbed a guy out to pull some trees off an embankment and haul them off for me. My Cat 248 might have been sitting in the ditch upside down if I tried it. Anyways, I talked him into letting me run it a bit. This thing was nicer than my wife's duramax. 6 air vents blowing, radio/CD, sealed cab... and it felt much bigger inside than my 248. The undercarriage looked much more open to me... The rollers looked easy to service... I don't know if that is a C change or not. It did not have steal rollers though. Also, it did seem like the machine was not as responsive as my 248. The guy that owned it felt the same way... said he couldn't flick the bucket like he could on his 246. I am really seeing no advantage to having an open cab. My next Cat will be enclosed if I am running it. I have mixed emotions on the tracks. It did spectacular on the slope hauling up trees, but he put a gouge in the brand new tracks down to the belt about 1.5" wide and about 14" long. I witnessed a few very choice words when he showed me that! Here is a pic of the bank.
