I’ve been interested in purchasing an R3 for some time now but I’ve noticed that most people that are selling them used on Facebook marketplace are selling them for about $5000 because they are trying to upgrade but the dealerships are selling them for $5500 brand new. What is what is a fair price for buying an R3? I really want to buy as my first bike, but maybe I’m not looking in the right place to purchase one.
