Well Amanda, it has been nice to share the forum with you.
Whilst it is certainly surprising news I don't condemn your decision. That Fiesta looks absolutely cracking. My friend has just bought a 1.25 Zetec model and I've been impressed overall by the car. I love the styling and I think it's one of the best cars for the money.
I wish you all the best with your new car and many happy miles motoring in it.
