Chris and Heinz,
Many thanks for your posts, that's just the kind of info I am after. Mine isn't a Sigma car but Chris your experience tallies with mine (except the hood - mine has a Simmonds hood which is fab. Of course it leaks elsewhere...)! I suspect if I did what Heinz has done, and fitted a Librands exhaust and manifold, plus SSL or the like front and rear suspension, it might be a much better car. That's not a cheap option though.
