If you have any common sence you will not have any problem with private sales.Do not let anyone drive unless you find the guy/girl fit to do so.When I bought mine he drove ,I just asked him to go through gears and hit all the potholes but firm but fair negotiation will get you more off than any dealer will give .

I'm in a similar position here in France selling my 22yr old well worn Disco, Its currently got 20 months French CT (MOT) & I'm asking a little over 900 euros, lets say hoping to get around 900 for it. Now at 900 & 20 months mot that 45 euro a month & you never know it may well pass another MOT which would make it about 20 euros a month as the French MOT lasts for 24 months. But no its not cheap enough, well sod it as it only costs me 14 euro a month to insure it I'm just gonna keep it till the MOT runs out then I'll scrap it, but I wont sell it to any of the silly bu**ers that have been to look expecting some lush Chelsea Tractor to impress the neighbours with. There, I said it. A weight of my chest!

Good luck to the OP with your sale.
