Classic Daimler - getting to grips with the faults

Since I bought the car I have not had much opportunity to drive it.  However I have been able to work a few things out.  I knew the paint work was not 100% when I bought the car.  Having had a proper look it needs more paint putting on it.  The pictures flatter the car, it was originally sable/beige and has been re-sprayed what I am calling Morse burgundy.  So at some point I am going to have to fork out for a partial re-spray, the doors are the most affected.

One of the other issues that I am not sure what to do about, if anything, is the seats.  They appear to look good upon a superficial inspection, but they have been almost spray painted with something very thick that masks what I suspect are some quite tired seats. 

One of the problems to be investigated is that it leaks petrol.  It is dripping gently from somewhere in the region of the tank.  I am not sure if it is the tank or some of the pipework leading into it.  Any thoughts anyone?  I have priced another tank, they are not cheap (approx £400).

One of the frustrating faults is that the drivers door does not lock or unlock on the key, so I have to lock and unlock it from the passenger side. 

Next time I will describe the dilemma about buying some wire wheels.
