A relative has a car for sale. Worth about 11 k. Advertised it on line and an interested party is due to see in the next few days. He appears very keen and wants to drive it straight away as he is travelling a distance. Says he will pay in cash. I thought it was a lot of cash to be carrying around and thought a draft with a few days for it to clear in the bank would have been a better arrangement. My relative is also worried about receiving forged notes. Any advice ?
