Can't say I've had any real terrible experiences, maybe we're lucky?
1. Quinlans - Polaris - they always treated our family tremendously, good pricing on new units, good value on trades, would drop anything to help us out. No longer in business.
2. Jansenns - Polaris- Went there after Quinlans closed up shop - one of the guys there worked at a marina on our lake, was a great guy - like Quinlans, always treated us well and were fair and good to deal with. Called Northgate now I think?
3. Performance Recreation - Polaris - moved there after Jansenns - this one came to down to $ - they offered me a much better dollar on a trade in - so much so I could not refuse the deal. I'm not a real dollars and cents guy - but this one only made too much financial sense at the time. Top notch people in there for me. Still in business
4. ATC - Cat - I bought my 2012 with a little over 100 miles on it from a kid that worked at a Cat dealership in Exeter. They are too far in the wrong direction for me to use regularly - so I picked it up - took it to ATC to get gone over, have some accessories put on - and we left for a trip. Super easy to deal with - did all warranty updates - treated me well. No longer in business
5. Carlsons - Cat - been taking my Cat there for service since ATC shut the doors, always been good - work done on time - no bullshit - you get what you paid for - nothing done without you knowing and okaying it - I've been happy with them and have no complaints.
My folks use Rickwards for their Polaris needs - they are very happy there as well.
No nightmares for me to speak of, have called a few places for pricing every now and again - but that's about it.
