I believe the Riley has quite a lot of timber in its structure, at least woodworm won’t affect the Traction
An awful lot of wood and the bit around the bulkhead is what rots most. I have watched one being ‘rebuilt’ over the past 5 years at a local restoration club and it still isn’t finished.
The Tractions propensity to ‘tinworm’ is nowhere near as bad and they are much nicer to drive than those old Rileys.
Good to hear you found an enthusiastic buyer.
