Parkers reckons £14,650 and What Car say £15,835.
ask the higher amount (you can always come down
1) Quite a difference between those prices - which is likely to be most realistic?
2) How much will the built-in sat nav, warranty and tax add on?
nothing but it will make it easier to sell against other cars
3) Assuming buyers will always want to haggle, do you therefore add a bit on to compensate for this so that the price your sell for is in fact the price you wanted to get, or do you just accept that you won't get the price you're after?

4) How realistic is it to expect potential buyers to be insured to test drive the car?
very unrealistic, especially for fully comp cover
