My late 2012 3 Wheeler has never broken down, but I've had a few upgrades. But original compensator, bevel box, engine, engine drive belt.
Replaced rear sprocket, and had comfort kit fitted last October.
Car running well but bevel box now noisier than it was before last service and seems to be getting slightly noisier as the miles go by. But that's the issue - because I'm so worried about the little wonder breaking down I am using it less and less and driving it short distances so it doesn't leave me stranded.
First year miles 2,900, second year miles 1,000, third year miles so far 450 and unlikely to break through 800 miles with mainly shortish runs so nothing gets too hot!
I'll probably persevere because it's a nice ornament and selling now would just crystallise the depreciation that is really quite severe given the running costs to boot. Has it affected my interest in staying a Morgan fan (I also have an Aero 8 for nearly 8 years - issues to start with but nothing too awful and very good since...)? Yes, 'fraid so. Pity.
