Were the exterior panels in good nick? Seats can be changed, and the engine rebuild kit includes all the bits that go wrong. Might as well go full barabus engine spec.
Reality is if it is cheap and you have the skills they can be fun.
It was a 450 698cc £650 so I’m not sure what I expected, but there was white smoke, a huge oil stain on the drive under it, what sounded like a knock from down low in the engine, the interior was hanging and smelt of mouldy milk. Surprisingly no rust though. Oh the tyres where shot as well.
It was a shed. Sounded like a bag of spanners being dropped down the stairs.
