Yep, new old fart here.
Don't have a diesel Cruze yet as I'm prepping my '02 Jetta TDI for sale.
I need to learn all I can about any quirks the Chevy has so I won't be taken advantage of when I find the "right" one.
Welcome. If you can wait a few months the new Cruze Diesel will be released and available. Chevy hasn't announced the actual date but it will be part of the 2017 model year.
To add what obermd said, the diesel Cruze was only built in the 2014-2015 years. It wasn't part of the 2016 year, as they were changing from the 1Gen to the 2Gen. It's expected to be back for the 2017 year.
