I misread the carfax. It was leased for 3 years then sold at 72k miles, or 24k miles a year.

The current lot changed the egr cooler before putting it up for sale.

I bought it and 100 miles down the road I get a CEL with code P20EE. The dealer said they will take care of it.

It drove great, it kept sneaking up to serious ticket territory.
