05's have fewer computer nannies than the 06's. Be sure and do an in depth check on any CRD you look at.Get a VIP report from a dealer. It will tell you any repairs done at a dealer since it was sold new. You will need the VIN to do this.
If at or over 100K miles on any CRD, check to see if the timing belt and all other needed items have been replaced!! Parts and labor would be over $1500 if it has not been done. EGR's were prone to failing quite often. A GDE tune eliminates that and adds a ton of nice enhancements. If you see any drips at the oil drain plug, it has been over tightened. There is only about 3 or 4 threads for the plug to snug up to, on the aluminum pan.
Check to see if the turbo hoses have been replaced. The originals did not have a good life span before failing. Just a few things to look for.
