Honest. Very professional. Prompt. Reasonable repair costs. I've been taking our cars here for over 10 years. Ivan, who manages the garage is exceptionally knowledgeable concerning auto mechanics and he always gives great great advice and service when maintaining or repairing our cars. In one occasion I took one of our cars to the dealership for recall work on the airbag. They then looked over the whole car and tried to convince me that I needed about $1,500 in additional repairs that I'd have to pay for. I wisely took the car to Ivan at the Shell station and asked him to have their mechanics look it over and advise whether the car really needed all that work. They could have easily checked it out and then told me that the car needed most of that work but not all of it, and I would have paid them to do it. Instead, Ivan advised me that virtually nothing the dealer told me was correct and that all I needed was some minor repairs for about $100! I won't take my cars for repair anywhere but the Tysons Shell.
