In a nutshell, I am getting a new car. The one I have ordered is no longer suitable (never really was, too small). I have found something much better and bigger.
Trouble is, the smaller car is already on order. I have spoken to the car company and they say its fine, I'm free to cancel, but I have to let the dealer I ordered it with know myself.
I just feel so horrible. How on earth do I just say "Hi, thanks for all the trouble you went to, to get me something quickly. But I've changed my mind".
I feel so mean. Also, what if he argues back that it's not too small, I should take it, etc etc?
I can't order the other car until this one is cancelled. How can I word things to him so I don't sound like a rude cow?
