Had that twice. I just laugh at them. Bloody idiots.
Also had the ones where they've mis-read or do not understand the window signs of p/m over 36 months. Or 36 months @ £x. Thinking the X is the total price of the vehicle in 1 sum.
Also when we were doing our Minimum Part Exchange deal of £1,000. Had some absolute lemon who wanted to give us his old Onion and £1,000 for a £23,400 Masa. I just stood there shacking my head.
Then just a few months ago, a customer talking to my finance manager doing a demands and needs I overhead them:
Finance Manager : "What's your monthly electricity bill?...
Customer : "I don't have electricity"
FM : "You don't have electricity in your home?
Cus : "Nope"
FM : "How do you run the kettle, TV, etc?"
Cus : "Oh you mean Leccy"
I actually face palmed myself.
