One of my friends bought a car from Houston for around $2k. A clean 2008 Cadillac CTS that ran rough but starts and runs with I think he said about 50k miles. No signs of interior water damage but it definitely got submarined. He had to get two connecting rods , two pistons and gaskets for the 3.6. We’ll see if he finds any other issues.

A Cadillac CTS picture for your time here, its not his car. I haven’t even seen the Caddy yet but I know its gray.
