I had the work to my mk4 supra done at rm motorwerks. My technician Colton was excellent! Very thorough and ocd with his work. He showed me progress along the way. He is one of the only people I would trust to touch my supra at this point. Now, I've now known roddy for a year and a half. He's a great guy. We have at times argued like a married couple over different issues, but always found common ground. In the time my car has been in and out for different reasons, there have been quite a few service writers, some good, others, fairly ignorant when it comes to vehicles, it was just a job to them (they are no longer there). Communication between done service writers to roddy back to writers and then to customers was lacking at times. Communication between me and roddy was always good tho. Prices on things can be rather shocking on some things. And sticking to certain prices quoted as best as possible would be good, but I do understand things come up. It's building a car, rarely does anything go 100% smooth. Roddy has always been friendly, even when I would lose my cool over certain things, but he would always try and do the right thing. I feel like at times, time management for certain things was lacking and one thing that I was never happy about, is that I requested that I get to see the car for a dyno run/ pull, which I never got, and was never offered during that time. It was my first time having a car on a dyno and it would have been epic for me to be there to see and hear it. But can't change that. All in all, my experience was good with a few hiccups along the way. I would rate everything as a whole an 8.5, which is very good by my standards.

Great performance shop especially for my high end cars. Thanks to Craig he is a Porsche owner and enthusiast that got my car running the best it ever has and no one else in the area would tune it. I didn’t think my Porsche turbo s could be any better but he proved me wrong. The launch control hits hard and brought my car 0-60 under 2 seconds. I highly recommend them and could not be happier!!!

RM performed $600 worth of unauthorized work on my car and wouldn't release it without payment. RM is 0/2 for the cars I've brought them. Both jobs turned out to be complete disasters, either in the short or the long term. Their work has been careless in several instances and extremely slow in all instances (usually months). Communication is consistently poor. I never felt like a priority here and RM did not take care of me as a customer. They utterly failed to be a trustworthy, professional, dependable shop. Learn from my mistake - stay away.

Asked three times for an estimate on a muffler delete. Took then almost a week to get it to me but still keep sending emails wanting a review. Seem more concerned with that. Estimate is $400 more than a few months ago, very strange? I'll be taking my business elsewhere. Almost $1,000 for a muffler delete is ridiculous and you shouldn't have to ask three times for one.
