Heater hose burst shortly after buying the car.
The alternator was replaced.
Brake switch underneath the brake pedal failed - easily replaced for under £5.
Rear brake pads replaced - watch out for sticking calipers on the rear brakes.
Drinks oil - 1-2 litres every 2 weeks - valve stem oil seals?
Radiator requires topping up every week.
May be losing water from the heater matrix?
This car requires regular attention to keep it in good running order.
A responsive car - lovely to drive - great handling and fantastic brakes.
Body work has no rust, but now looking shabby.
The coolant leak, if not in the engine, will definitely be the heater matrix. Check if the carpet in the passenger footwell is wet/sticky. Check the O-Ring seals on the two pipes going into the matrix.
