It really is a great day at Billion

Reviewed by FloridaMan in Bozemans, MTMay 28, 2021

They answer the phone "It's a great day at Billion" and it really is. Everyone there is very nice and friendly. I just had three cars serviced, snows swapped out, oil changes, etc. They also did major repairs for serious problem I had with a brand new pickup purchased from a different dealer and did an excellent job. I will note that the reviews that complain about the wait at "Express Service" are probably not incorrect. I appreciate the express service because I don't need an appointment and just drop the car off, and I'll get a call sometime before the end of the day - I never hang out and wait for the car to be done. It's a good practice in life and time management to never depend on something happening at a scheduled time if it can be avoided, and its very frustrating to wait for something and have an unproductive day.

Worst service experience in more than 10 years doing business. 3 hrs for an EXPRESS oil change. At 1.5 hours asked how much longer and was told 1 more. Why didn't you tell us at beginning, " you didn't ask". Shame on them.
