David, the service manager at Callas, is terrific! He really knows the cars and explained everything that was done very well. He's also very polite and courteous. He could work for a Porsche dealership but he's too good for that. You better keep him happy :). As for my car, I could not be happier. Its 20 years old and almost 160,000 miles on it but now runs like it did when it was brand new. I will have any future work done at Callas and will recommend them to everyone.
