I was leaving for a month long camping trip and learned that the car needed a battery tie down. The folks at O鈥橰eily鈥檚 not only helped me find the right parts but installed them for me as well. It was a lifesaver and a huge relief, allowing me to start my trip on time. They were so friendly and generous and just good souls. Thanks Ken and Will!!!

These guys will send you looking for a part number that doesn't exist on their shelves. Don't waste your time here, both AutoZone and Advanced Auto are way more friendly and actually want to help. I felt like a burden to these guys to ring up one item

Staff is always available, friendly, patient, and helpful/informative. They always have the answers or are willing to find the answers right away. They're as helpful as you need them to be, but always respect if you wish to do certain things yourself regarding your own vehicle. One of the few places around that still staffs well enough to ensure the phones always get answered in a timely manner as well! We'll be back for as long as we live nearby :)

It was a dark and freezing February evening when I was replacing a wiper blade on my niece's car. Unable to replace the existing blade, I made my way to O'Reilly Auto Parts in Castle Rock. I was promptly greeted and helped by Dalton. He quickly identified the appropriate replacement and informed me of the BOGO sale in effect (providing me with the passenger blade I needed and the drivers for a future date). He explained to me in detail how to install this model and offered to do the installation himself (but I didn't have the vehicle with me). Upon returning home I was able to install the new wiper blade and get out of the blowing snow in just a couple minutes! Dalton is a friendly and caring professional who is an outstanding representative of his store and the O'Reilly chain. Thank you very much! Eric

I stopped in for a a question about my Altima earlier today, I was very quickly greeted by a younger man at the first register(didn't catch his name, light brown hair, ball cap). As I waited at the counter to ask a question, I was over looked for several minutes while the other man working stood leaned against shelf on his cell phone. Irritated as I was, I tried to make conversation, very much wanted someones opinions on my options. And this man, James, couldn't be bothered. When I asked for a Manger, he stated; he was the Manager? Not a good look for a busy place of business in Castle Rock-

I miss Brandon. When I walked in the door, I was greeted instantly l, and never had to wait for more than 30 seconds on any help, or checking out. Never been the same without him. I order parts online from a competitor now-

I just saw a review earlier that someone said Autozone has a cleaner feel and a freindlier staff... lol.... I almost never go there... First of all, if you really work on cars and are not just a poser, you would know what really matters at a parts store are these two qualities: KNOWLEGABLE and HELPFUL... With that said, Curtis is one if the most knowlegable parts guys I have come across in my 35 years of working on my own cars...and I mainly work on Audi's. Curtis is usually knowlegable about what I need and always helpful, even when he doesnt have what I need, by letting me know quickly and not wasting my time....anyone with a job half done in their garage will understand how important this is. They have fair prices. They can usually get what I need that day if its not in stock and hold the parts til Im able to get there and pick them up. They have the best tool rental selection in town. I use a few parts stores in town, as anyone should, but these guys are my go-to. I just picked up this Power Torque 73 piece set PURELY because it had 1/4" drive hex keys down to 3 mm. I heavily use the 4mm, 5mm and 6mm keys and I was tired of chasing the bits that fall out of the single interchangable socket and fall behind the motor while working on this 1.8t coolant flange.. Thanks guys and THANK YOU Curtis!

I came in and was having difficulty with my hood latch popping up The manager, Doug came out and oiled the latch and tightened it for me. He would not take any money . I had 700 miles to go so appreciated his kindness very much.
