Had an absolute horrible experience with this guy. Brought my car in for an oil leak and after 2 weeks of him trying to find something else wrong with the car he finally got around to repairing the oil leak. He called me stating that the oil pressure relief valve was stripped out and that he could not find parts. When I told him he had replaced that part last year he didnt have anything to say. I was able to find the part in about 5 minutes and sent him the link. I got a text the next day saying he would warranty it. When I went to pick up my car a week and a half later he blamed the botched repair on the car and complained about how much money he lost. YOU DAMAGED IT! How does a non moving part cross thread itself? At this point I wouldnt trust him to fix my wheelbarrow. Id be farther ahead to take it to a Porsche dealer. I recommend this place be avoided

Very honest, trustworthy, and reliable to get the job done, regardless of the problem(s). Other mechanics would have given up but Charlie will do anything and everything possible to get you back on the road.

Very helpful and informative. Would recommend and return for future services.

Charlie is hands down the best in quality and service. He goes above and beyond to take the best care of your vehicle as possible.

Changed out the starter for my 2011 BMW 335i. Worked with me on the price. Did quality work. Very clean shop. Would recommend.

Very thorough at doing the repairs properly to ensure quality service.

Charlie, the man who owns this business, is like no one else you will ever encounter when you take your car in to be worked on. I mean that in the best possible way.it was a Saturday morning this past May. I needed just an oil change in my 99 SL500 before getting on the road back to Colorado and I didnt have an appointment. poor planning on my part. initially when I met and spoke with Charlie, he said that I would have to set an appointment for Monday. I said not possible, Im leaving later today so thanks anyway. Ill just head over to (forgotten oil change place) and get it done there. Charlie paused and said I cant let you do that. can you come back at 11am? I did, and he proceeded to take excellent care of my car. I had nowhere else to go, so I waited in the shop area while he went to work on my baby. I was impressed that he uses Mann filters (Benz recommends them) and in addition to my oil change, he took the time to bring me over and show me a couple of things that needed attention even though he knew I was leaving and he wouldnt be doing the additional work. he explained things in detail that was very understandable to me. Charlie is a kind, intelligent, and highly skilled man that knows that the European cars that we have a passion for have a soul. he is in touch with those souls. Im now back in Colorado searching for a new mechanic that is at least half as good as Charlie so that I can keep my Benz in good mechanical condition for as long as possible. if Rennsport Tuning wasnt 5 or 6 states away, it would be the only place I would take my car.

If you have a euro car you have to visit this place! If you love your euro car Charlie should be the only man you let work on it. Beyond impressed with the service they did on my BMW. Extremely knowledgeable, very good attention to detail, super kind to deal with. I will certainly be back!

True top-level work on some of the most complex and temperamental cars ever made. These guys will get your car to run the way it was always meant to.

I have a couple of older BMWs that Ive taken there for service. Ive owned and worked on my own BMWs for 30 years. When theres something I cant fix or dont want to fix I take it here. These guys know their sh#t. And theyre honest. And their fair.

Great group of guys... You can definitely trust them with your car. Theyll give you the best, affordable tune-up on your vehicle.

Did a great job, very knowledgeable and car was done n a timely manner.

Excellent Service from Charlie

Excellent service done quickly!

Highly recommend. Very knowledgeable, fair prices, great personality

Best in the business hands down!!!

This is one of those gems you might hesitate to tell people about because it will become too popular. Be assured that when you take your vehicle to Rennsport, especiallty Porsches, that Charlie and his team will give you the very best advice and service at a reasonable price. I dont know where else youll find a mechanical engineer to serve as your mechanic.

Excellent import mechanic.

This guy knows his stuff.

Excellent service.

Great work

Not good
