I've used Jeff's several times. They are always very clear about what they are recommending, why they are recommending it and what it will cost. The quality of their work has always been top notch.
Although their prices are not the cheapest they still charge much less than the dealers do and their work is much better in my experience. After owning 30+ cars over 35 years and having used at least as many mechanics, Jeff's is clearly in first place in my book. You might be able to find another independent mechanic that will do a specific job for less money but I haven't found anyone else that has Jeff's consistent quality of work and communication.
