Nice looking car Ben, as regards the issues those are broadly in line with a friend a few doors away who got rid of his because he was sick and tired of it, the unreliability and as you say the sheer cost, he bought a 13 Plate Merc C63 Coupe and guess what it's the same old story, such a shame as they are both charismatic cars.
Now you have been to the Cotswolds in the rain I guess, you were not far from the favourite ISF Cafe AV8, more of that another time , welcome to the fold👍
