I bought a BMS-150 ATV from this couple 2 days ago and it was a great experience. The sales rep was really friendly and seemed really knowledgeable because I asked a lot of questions. The cool thing about this company is the prices are really cheap AND shipping is free. They also have extended warranties available all the way up to 3 years. I couldn't say enough good things about this company.
