Would like some advice please chaps.

Have the unenviable task of selling my recently departed fathers car.

Think I値l have a go privately selling first off, but not sure of the safest way to ask for payment. Question: is it unreasonable to ask for ｣10k in cash or seeing the funds transfer direct into my bank (2 hours these days???) before handing over the keys? I知 paranoid that a bankers draft could be fake, with the car then long gone out of sight. What is reasonable to ask the buyer without being too onerous for them?

Anyone , thanks?
