Don's is awesome! You don't need an appointment but it can help you get on the road faster. Don's will always try to work you in even if you walk in off the street! QUALITY work, GREAT prices, HONEST people! It doesn't get any better then Don's. Still family owned by the same family. I have been going their for about 20 years now. They also do inspections and breaks now too! Go in, drop off your car, have lunch at any of the fine restaurants nearby or just browse the local grocery or bakery or just stop down the street for a beer, as well as several other cool stores within walking distance.
