I detected the smell of burnt smoke inside my car. I went to Hendrick Buick, they told me they were going to charge me $3,500 to replace my head gaskets. I decide to go to sci-tech to get a second opinion, turns out they found the problem and it only cost me $322. Ari and his team of technicians are knowledgeable, fast, professional and honest. Needless to say I was totally satisfied and I will not be going anywhere else with my automobile problems.
