Someone paying in excess of £30k for a car will want it perfect, the refurb shouldn't cost much more than £100.
Also agree the photos aren't doing the car any justice, you need some better ones.
As you have identified yourself it's a niche market you are selling into as not many spending that kind of money will want a 2 owner car and would rather deal with a main dealer for a brand new car.
