Just picked up a 2014 Cruze Diesel. Only had 37,000kms on it, dealer maintained, and so far it's been wonderful! Hoping for many relatively problem free miles out of this one. Previous car was a 2000 Toyota Camry with just over 200,000kms - this so far has been a fantastic upgrade!
Poke around the diesel section of the forum a bit and make sure to familiarize yourself with the signs that the car is in regen mode (they get mad when they're interrupted in the middle of a cycle too many times). There is also a bit of reading there on sensor issues with the 2014 CTD, but otherwise, they're relatively trouble-free, and we wish you a happy and trouble-free ownership experience!
