1) Diesels hold their value much better, and a lot of times because of the finance rate it pays to pay 2-4 more thousand for a new one. Plus, it's new! :D
2) Finding a used EcoDiesel was pretty tough awhile back ago because of how new they were.
That 60 month thing..yes, it makes you think about skipping that new truck. I sure thought about when buying new.
Good GM story, I've had may GM trucks that never gave me any problems.
Since you have the problem documented under the warranty period, I would hope you shouldn't have a problem moving forward if it does happen again.
On the plus side, if a EcoDiesel owner is out of warranty and the (Expensive) emissions equipment does break, we'll have options soon to remove it...
Mine was full upon receipt. It could be a dealer option to decide how much to fill, but I imagine they have a pre delivery checklist that has to be completed and I'm not sure if filling the DEF tank is one of them. It's not hard to fill it up though...
Off the self products, ICE makes some nice stuff. I've been buying everything online from a few different sites. ChemicalGuys.com is one, and AutoGeekOnline is another.
The spray foam is awesome to use!
