Here's Ken the shop owner explaining his diagnostics of what's going on with this customers engine. This is what years of experience sounds like!! Come check us out anytime and you'll get an honest diagnosis. If we can't fix it, we'll let you know and recommend you to someone who can. We don't oversell you on stuff you don't need, either. We'll let you know what we think is coming up and how long you can wait on it. We don't do anything without informing you and making sure you're okay with what we're planning to do! R&D has been open for almost 11 years now and we pride ourselves on being honest and fair to all of our customers! We're family owned and operated and have the best mechanics in Colorado 😎 #firestonecolorado #longmontcolorado #firestoneauto #firestonerepairshop #carmaintenance #truckmaintenance #coolcars #familyownedbusiness #familyoperated #family #safecars #honestmechanic #honesty #loyalcustomer
