I came to find Demo's as a Rice student and continue to use it 5 years after my first service there. From routine diagnostics to installation of a new battery to transmission work, their service has been expedient, well-executed and fairly-priced. This is the first car shop I've found where the mechanics take the time to thoroughly explain their work and lay out all of your options plainly so that you can decide what needs to be done now, and what can wait until later.
To illustrate the personal investment these guys take in their work, here is my last Demo's experience: My transmission began working up one week before I had to make a 16 hour road trip. They not only serviced my car well, but also called to be sure I had made it safely to my next destination. I recommend this business personally to any friend looking for a repair shop, and I recommend it to you, too. You will be pleased you came.
