The D & A Performance Automotive shop is located near the Stor- IT storage facility in the Capistrano Business Park. It is a small shop and is able to service only a couple of cars at one time, but owner David Moatakef and his team are fast and efficient, which means a faster turn-around for the customer. It is also a certified smog testing site and exhaust repairs is one of its main fixes. It also does tune-ups, oil changes and A/C charging or repair for both cars and trucks. The shop also boasts a computerized diagnostic machine that can pin-point those hard-to-explain concerns. D & A can also repair minor dents and scratches, but it is not a shop that can refurbish cars that have been in a collision.
