Had my 2011 V8 Calais V sportwagon from new (currently has 180k), haven't had any major issues so far, although the transmission is starting to flair on the down shift from 3rd to 2nd and then shudder into 1st when coming to a stop, but im having that looked at in a few weeks time, service is done every 5-7k ks and I lose roughly about a liter of oil but no more.
