We all have our opinions on when’s the best time to buy an ATV. Generally from my experience the best time would be after summer or the end of September. There are a lot summer deals but I notice its easier to negotiate with dealers when the month is ending (I think they need to make the sales quota). I consistently get awesome deals when the summer season ends. Getting last years model also helps a lot in getting the price you want, but I notice even the current models are price really competitively during this time.
Heres a great Summer deal from Artic Catwhich I think makes one of the best ATVs in the market. I would skip the 2009 and bellow models and stick with the 2010 to 2012 ATVs. I notice a lot of changes in the 2010 models which makes them a great buy if your looking for an extra ATV for a yourself or a family member.
