I'm usually open to negotiating and especially like helping the guys that i know for certain aren't too well off, makes me feel great knowing they have a toy in their possession they would not have been able to afford new

When i purchase second hand goods and the gent is courteous, well mannered, the equipment is in good nick and the price is reasonable i will not ask for discount. If the goods are not as advertised i will let them know of my dissapointment and offer price X. Some peoples definition of "excellent" , "as new" condition is beyond me especially in the car trade

Must say most guys on this forum i have met personally and they are really great chaps. I therefore usually advertise here first and if unsuccessful and i am in desperate need of moola i will resort to Gumtree/Junkmail
