Carlos is so amazing! He is very efficient yet thorough, and will tell you flat out whether or not he thinks it is a good deal. He gave me advice on smaller maintenance strategies, shared his knowledge of dos and donts, and helped me figure out some specific features. I also got to sit with him in the car while he drove it around, which I really liked. He explained what he noticed and felt, and why he was doing certain things. Having Carlos check it out made me feel much more confident in my purchase, and I felt a lot less nervous taking the leap. I plan on calling him back up down the line for anything I need. In the end, I was able to drive (not walk) away in an amazing 2003 Mercedes Benz SLK320. I really appreciate his help and advice.
