Shame things have come to this. Gald you didnt get stung though.
I actually got cash out ready for my car purchase, at the time I was looking for a 147 GTA and knew I'd have to travel far to get one, so to save trips I had the cash out and ready to go, I thought all buyers would be fine with this. However first GTA I went to see the guy said he wouldnt take cash, and then the Z4 came up and I went with cash too - he also refused to take cash and made me go the next day with him to pay it in to his bank.
He was a policemen too. Fair enough, I guess when dealing with such money no deal can be done on the spot anymore, its best both parties go to the bank to get things done and veryified. I barely slept that night!
I guess looking back we might have looked dodgy, 2 young lads turning up in a Porsche, and I didnt even drive the car before agreeing to buy it (my mechanic mate did though).
