By far the worst experience I have ever had with a business. They produce sloppy work and will not back what they do one bit. Once a problem does arise they will become aggressive, hostile, and try to bully you. The customer service is good when you are getting the work done and are about to pay them. Once you have paid and the works been done but if their is a problem with the work done all the customer service goes right out the door. I lost thousands of dollars because my engine was not rebuilt right by funk e built. When I came to them with the problematic motor it was instantly not their fault, had to be a part failure. Almost instantly they quickly changed it all to being my fault that one hose wasn't connected on my car when it left their shop. Telling me it was my responsibility to ensure my car was completely good to go, after they did a full motor rebuild. They didn't complete my car when it's left their shop and when it came back with a problem because of them, they instantly turned hostile. On top of that they blamed me for my car leaving when it was not 100 percent completed, yet they put it all together and released it to me when they deemed they were done. On a side note they also didn't put the nuts on the motor mounts, so my motor wasn't completely bolted down. This company sat and lied to me for weeks about the health of my engine. When I knew it was messed up the minute it left their shop. Do yourself a favor and stay away from here. You'll save so much money. You'd be much better off with choosing any other shop in Colorado. This shop is so unprofessional that they deleted the Facebook page they had because of negative feedback. They then started a brand new page with all five star reviews! Goes to show that they avoid and cover up problems. Rather than dealing with them. Thanks for taking time to read this, I hope this doesn't happen to any one else. It sucks losing over ten thousand dollars and being blamed for all of it. read more
