i sent this email back to him:

Hi,

the price has gone up to £6000 due to other cars fetching that sort of money. If you are interested, send me a bankers draft for £10,000. I will then send the remaining £4000 back to you in an envelope inside the glove box.

Let me know if this is ok for you

Look forward to hearing from you soonest

Thankyou please

Rich

Lets see if he responds
