I've seen Ford employees on these boards offer the codes to people who asked - if you (or a family member/friend) aren't looking for a new Ford product, then the code is useless to you, anyway.
The x pricing plan is actually offered to quite a few people - I remember a co-worker of mine bought several cars with the plan, her daughter worked for a finance company, which was a subsidiary of Ford. Transamerica, I think it was.
It saves a large amount of $$ - and the haggling you would have to do without it. Makes the car buying process much less painless, IMO!
Good luck with the Edge - I think they're great cars!
