I've landed a new job with gives me a car allownace, so looking to ugrade my current A3 2011 to a newer A3. But I'm getting confused with how part ex works with a car on hire purchase. The settlement figure is £6073, and an estimate part ex value approx £7500 (i need to go to the dealer to get an exact figure). The new car I'm looking at is around £13000 and I'm going to go through the same dealer who arranged the hire purchase as well. Am I right in thinking the part ex value of £7500 will go towards the deposit of the new car and I have to pay whatever is outstanding?
