'Semi' outcome. I found a car at my original dealers and as part of the process they take the car as part exchange. The original finance was set at 8000 miles per year (32,000 for period of contract) I actually did 10 over the 4 years. Despite this and the car being in excellent condition, they offered me £3,600 (£250 equity). The salesman actually suggested I try Webuyanycar. I got a quote online for £5,000. I took it to them and after a ridiculous amount of scrutiny - tiny paint chips etc. they knocked it down to £4,000 take it or leave it.
At the end of the day, the finance is settled, I have the deposit for the new car and £350 in my back pocket so I'm fine with that.
There is one thing however, he said it would take 5 working days for the finance settlement to go through. It never crossed my mind at the time but I have a deposit on another car which I now can't finance for at least 5 days. So as it stands, Webuyanycar have the car and the money for the next week. This is ridiculous.
