- Looking to trade in my 2018 Colorado. The transmission is junk and has been in the shop 5 times in 18,000 miles. Looking at a 2015 Crew Cab Silverado. Should I stick with a 2015 or step up to the new front ends of the 16-17 Silverado? What are the pros and cons. Looks like I need to update my signature also. My 07 I sold to my father in law and wish I would have kept it.
