So - i have a car on PCP, lets say it's a Mazda from a Mazda dealership, coming to the end of the 4 years contract. (car itself is now 6 years old).
I've heard that you don't have to go back to the original dealer with the car at the end of a PCP. That if, for eg, i wanted a Range Rover next, i could take my Mazda to a Range Rover dealer and ..... do what?! 
?? how does this work ??
TIA
