  Aziz and Austin have taken the best care of my car. My first experience with them was getting my turbo coolant lines replaced which they did at a third of the price of what I was quoted at BMW of Rockville. Next up was brake rotors and pads. I also had an issue with my headlights which they diagnosed and while it was recommended to replace the headlight, they also gave a cheaper unguaranteed option to re-ground one of the wires, but they said that may not last. While unguaranteed, they did great work as it is still working months later! Now they are helping me restore my car to like new condition with a few upgrade after I bought it used with a few issues.
  
  It's one thing to go to school to learn to be a mechanic, but it's another thing to have the passion that they do. Instead of taking my car to a mechanic, it's like taking my car to a friend. I can't express enough of their value in expertise, trust, fairness, and passion! They have become a partner and share in my passion as well. Thanks guys!

  Aziz and Austin got my BMW 335i back on the road after replacing a bad turbo. Nothing but great things to say about the guys at Rennwelt.
  
  Great customer service and extremely fair pricing!
  
  I would recommend Rennwelt to any BMW owner 10/10. I don’t plan on using anyone else ever again!

  Excellent experience and service from the guys at Rennwelt. They worked to update my engine management system in my BMW 2002 and got the engine tuned/running strong. Highly recommend their work.

  Absolutely fantastic experience here. I had my Audi s4 4.2l V8 rebuilt and installed here. They did a great job considering they we'rent even there for the disassembly! These two guys know their cars. Easily the best decision I've made with my project. These guys aren't afraid of large jobs or project cars. Great work guys!!!
