Ford KA or Ford Fiesta?

[MsMiaWallace]

Currently have a fiat 500 & looking to buy a new car soon.
I'm interested in the KA's or Fiesta.

Which ones better? I appreciate one is bigger than other.
Any owners on here?

They are great cars, my first one was about 16yo when I got it. I paid £350 for it (practically my first car, I had a polo for a couple of months first) barely had a problem with it, until the end. I think I had to replace the motor for the windscreen washer water, and one or two other minor things but I had that car for 5 years. I can't remember what went on it in the end, and I don't know what mileage it had done. I'm still sad about scrapping it now. Me & that car and my dog had some great adventures.
