I had owned a Lincoln at the time and the oil change was free because it was a Lincoln. This is a good deal. I also bought the Lincoln from Dahl. They were very friendly and helpful. Excellent staff and very satisfied with them. My mother in law also uses Dahl and she seems to like them too.

While the rostationd and oil change went quickly, but the extra work offered quickly turned into added hours. The bolts were rusted (WI car) so the service manager ended up taking over. He was forthcoming about how to slowly take care of everything.

I took my car in at 9 a.m. and left it asking for the oil change to be done by 1 p.m. if possible. They called me at 10:45 and said it was done! The guys are always professional and the price was great.

They were very helpful and told us about the rebates that we can get on the water heater. I was at work when they came. They put all the needed information and told us about the rebates that we could send in for with the new water heater. They were very prompt with coming as our water heater...
