In the past have purchased vehicles from the dealer with the best price, the dealer with a great reputation for service and a dealer that was convenient to home or work.
Jobs have a way of changing over time so picking a dealer close to your current work location may not be as convenient if you change jobs. Same thing if you planning on moving in the next few years.
Years ago I purchased two vehicles from the second largest Saab dealer in the USA only to have GM award the Saab dealer franchise to a competing dealership. Yep, that can happen. Luckily I found a dealer that was close to where I worked.
I would balance dealer reputation with price and location when considering purchase of a vehicle and realize that things can change.
