I cant stand places like this that take advantage of people who dont know much about vehicles. This guy saw that our check engine light was on, proceeded to run the emissions test anyways, then waited to tell us afterwards that we failed ONLY because our check engine light was on. A decent human being would have recognized we are a couple of girls who are misinformed, explained right away that the check engine light being on would warrant an automatic fail, and simply told us to come back for the emissions test once we got that squared away. Central Denver Diesel, enjoy your $60, because youll never get business from us or anyone we know again.

I rarely write a review for any business. I called and ask them the price for an emissions test, which they quoted over the phone. In their office they have a price chart, confirming the price quoted over the phone. Upon arrival for my appoint I asked them again about the price, just to confirm. After they completed the test I was charged $20 more than they had quoted. Beware. There are better option, more honest, option available in Denver for an emissions test.

It was good the place I use to take my diesel in for inspection. The inspector had moved out of state so they shut down inspections.

I was here for emmisions testing. Thank you for your quick, efficient service.
