I'm thinking of selling our Cayenne and downsizing a little. We never really used the huge amount of space, so would prefer a smaller car and the ability to stick a roof box on it if we ever need the space. I was wondering if there's any steps you lot take before selling a car like this - this will be the first private sale by me as other times I've traded in with a dealer. Also, will I be paying income tax on any of the money from the car? It was bought on lease if it means anything. I use this salary tool to figure out my earnings - should I add money from the car from that?
