My prices are almost always set in stone so I declare that it is "firm".
Anything under 4k is cash only.
Local sales only, no delivery or shipping.
Absolutely no trades
I have a truck on CL right now and it has been the dumbest series of emails I have ever gotten for a vehicle. Pics and description including the good and bad but still they ask how much or what year...one guy was trying to haggle the price and hadn't even come to see it yet.
