"PA safety and emissions while I waited. Waited with cable TV, multiple choices for the Keurig, while I sat on a comfy sofa in a finished and painted and decorated office which was more of a living room than a waiting room. So while using their WiFi at the same time, in the nice, warm customer area with 2 professional staffers behind desk entire time answering calls from tractors & trailers on PA TP, 222, etc, but my 1993 passenger vehicle which had seen better days was attended to by Jimmy, who even after passing and placing stickers noticed a marker bulb not operating correctly when I went to pull out. Even after I had already paid (for not much more than the stickers!!) and had my stickers, and was ready to leave, he made sure to pull the light assembly out, repair the bulb socket, and replace my bulb, which worked, with a better newer bulb (free), just to be sure. No extra parts or labor. That’s just good business. Being a mechanic and shop manager in the past, and a guy who likes to bring my vehicle for inspection knowing it needs almost nothing, I was far from let down at the work done by Evan, Jimmy, and the whole 10+ person team at Denver Diesel & Automotive FKA C L Martin. Thanks so much, guys!!" - Greg
