Quite straight forward, enter your details on the link and book a test drive, once you've done the test drive you'll then get a voucher code which you put into the link. Easy!
We have a Fiat dealership very close to us and were actually thinking of buying a new family car so thought we'd give this one a go even though it had never crossed our minds! But now its jumped to the top of the list! Loads and loads of space and you can have 5 or 7 seats. Not the best looking car out there but the kids love it.
