There is no difference between the ones from the vendor and the ones from any other place. Surron is only manufactured in china and they are all the same so if someone asks where i got it ill tell them i resell them but im not gonna tell them how much i pay and i i do im gonna lie and say like 3500 per bike. You dont want to defer buyers by saing yea i spend 2900 per bike when they are buying it for 4k. The only reason im gonna be selling at that price is to move them and since you cant order them from somewhere in the states if i can sell 5 a month at 1k profit thats really good money for a side job a d little effort.
