Had my head gaskets go out on my 06 F350; after some shopping I found Drew's Diesel Repair (DDR). There were plenty of Diesel mechanics between my house and where Andy was located, but his reviews brought me to his shop. Called him and got a fair & straight forward price. Asked how long I would be without a truck and got it back in that time frame. On my way home from DDR the engine noise was so loud in my cab I couldn't hear myself think. Called Andy and he sent one of his techs out to my house, 2 hours from his shop. Beyond that, they waited until it was convenient for me after I got off work. Turns out one of the pipe clamps on my aftermarket exhaust was touching my firewall. Something simple that I could have done myself but Andy insisted his techs fix it. He has made a customer for life out of me. Thanks bud for being an honest mechanic and business man. If you're in the midwest and need a diesel mechanic DDR is you place.
