Well, I went ahead and bought the ex-taxi and I must say I'm very pleased with it so far. It has 131k miles but (touch wood) it all seems to be working just fine and the LeafSpy isn't showing anything concerning. Fast charge socket ordered but managing with 3pin for the moment. Drove from Driffield to Milton Keynes yesterday, at 185miles I ended up having to stop 3 times but luckily avoided the broken chargers on the M1. Drives well but ended up having to follow a few lorries to get anywhere near a decent average speed.
