I bought one of these in the spring with a rebuilt head and rebuilt transmission. I really liked the car and own a 300sd, but I could not get it to run as well as I would have liked and I've read a lot about them and took as good a car of it as I could but it threw a rod I think, going highway speed it made a huge smoke cloud I pulled over and tried to stop it but it kept running and … revving and then stopped. Basically totaled. Take my warning, I had read bad reviews of the engine but didn't pay attention.
