I had to have the door panel re sprayed due to the door being out of line on the lock.
This was done under warranty and the car came back as good as new.
Apart from that my only problems is the lack of glove box light and no buzzer if you leave your lights on.
The car is very nippy for its engine size and came with quite high spec levels.
The car came with air con,power steering and alloys
My car is in red and looks well good and sounds the biz now thanks to to performance exhaust on it.
You should definitely have a "lights-on" warning buzzer - I have this feature on my 2000 Fiesta, and am pretty sure it has been a standard feature since about 1995. The buzzer should sound whenever your lights are on, the ignition is switched off, and the driver's door is open. If it doesn't, then you have a faulty buzzer which you should ask your dealer to fix.
Just a note, I have a fiesta freestyle and I have warning alarm when I leave the lights on, so yours is certainly faulty.
