Price for x7

yo im gettin a s-10 so no need for pb no more (i might keep it) how much should i ask. im gonna sell by news paper and local shops have sold some for 700+ for a cateye.. luckly i went 2 hrs. away and got an x7 for 300. ppl in my town have lots of money for there kids (every family has at LEAST one or more mercedes, some times farraris) and i wont feel bad by over pricing. By the way i have led lights(all except head lamps), tuned carb, performance filter, and boost bottle and goes bout 37mph
