These numbers have to be taken with a little pinch of salt as we're dealing with a broad range of cars and at times (particularly last summer) there were very few trade cars on the market. And more importantly, Maranello Autosport had a 34k miles manual car for sale for £23k for 6 months last year, which totally dominates the numbers. I had to fudge things to eliminate that car. So the graph below shows prices for: only trade advertised cars with between 35k and 70k miles; only autos. Over the period, average mileage stayed fairly constant at around 55k.
It is hard to be 100% confident in these numbers, but they do suggest price rises from Feb '15 to Feb '16 of around one third, with a positive underlying trend if you can look past the bouncing around in a thin market last summer. The April 1st '16 data seems to have gone missing from my Dropbox, but as of now, the average price for all cars with 35-70k miles is £15,924 and for all autos is £16,135.
