I have done a considerable amount of research, and I am planning to purchase an Eton Viper 50M on Saturday. I have looked at the Polaris, Yamaha and Kawasaki. My son is 4 years old and this quad fits him well. The 70 is just too big. Can anyone offer me any last minute positive or negative feedback before I pull the "trigger"?

Thanks a bunch,
