tonym: I would love to add items and issues specific to the UK, but would need a "deep immersion" experience in UK acquisition, import, servicing, warranty, and regulatory issues!
Are you offering to have me as a house guest for, say, two weeks, with multiple get-togethers with other UK Fanatics, so I can get that on-site immersion?
p.s. One way of addressing getting GOOD service is to help a competent centrally located private hi performance shop get started as an "SSR specialist". This requires some organization by a committed group of owners to make it viable for a shop.
