In my experience time and/or work/family/financial pressures are the key as to how to sell...
quick n easy, RELATIVELY little hassle = WBAC etc!
I once sold wifey's Yaris at auction and got more than WBAC.
After all WBAC have to sell this on, to trade presumably, who will then sell on again to someone who may eventually appear as an owner on here?
That's at least two dealers who need to make a living out of this car.
PS - if you know someone who dosen't mind loosing money, please pass their details to me - by PM of course!
