This is a great shop.
I blew a wheel bearing on my way west and they had it switched in no time. Mike and Steve are great!

I look for a few things in a mechanic:
1) Honesty
2) Good communication
3) Availability
4) Good prices
At Rieger they knock it out of the park on every one! Great people, I'm glad we've got such a good place here in New Castle. I'd highly recommend them to anyone.

We were having transmission issues on the way back from a trip and we took our car here. They got us in quickly and did a complimentary check up on the vehicle including adding transmission fluid. They told us to head to a transmission shop in Glenwood to verify their diagnostic with transmission professionals. Thanks Rieger Performance Motors!

They did a good job fixing steering issues on my truck. It was done quickly and the mechanic gave good feedback. I feel like I trust this shop and will continue using them.

The team at Rieger was really nice. They looked at our van for 30 minutes, added some fluid and then recommended we head to Glenwood to see a transmission specialist. They didn’t charge us which they could have which I think was very honest! I would trust them with other work.

We were traveling home to southern Colorado when our truck died on I70. We contacted some friends we know in New Castle and they recommended we bring it to Rieger. We had no appointment and they got it diagnosed and repaired in the same day. The price was great and the customer service was top notch! Thank you Rieger you made the best of a bad situation and we can't thank you enough!!!

I took my truck to several mechanics in the valley and nobody could/would fix the problems I was having with my truck. Took it to Rieger and they fixed the problems and let me know some other things that were in need of replacement. I will be taking all my vehicles here from now on. Happy to get my truck back in good working condition finally. Thanks Rieger!

I was able to get my car in quickly for new tires. I mentioned that a shop in Denver had told me I needed new struts, and they said they'd check it out. Turned out, I didn't need new struts...and the shop in Denver may have just been trying to get some extra $$ out of me. Fast, efficient and HONEST. I live in town, and they gave me a ride to my home and came to pick me up when they were finished. SO HAPPY with the service here. 😊

Small town customer service and convenience. Good hardworking locals. Quality work that surpasses all "big box" competitors. The only reason I use any other Automotive service is for warranty reasons.
