Don't worry mate, not starting an argument, I`m thick skinned enough (someone said beauty is skin deep, and I have deep skin, lol, think it was the wife)
As regs we do get a lot of enjoyment by helping others, but there is always some negative comments so it does get annoying sometimes.
Personally I think sapphires are starting to increase (and sure many agree) as RS500s increased, then 3 Doors, now sapphires are the next cosworth people are looking at.
Also a lot of cosworths have either been crashed, rotted or broken (but used to repair others), so they are all getting rarer.
Either way it is good news for us owners, but it can push prices beyond others.
The valuations on my cars are not done by myself as we have to get others to value them for us, for obvious reasons.
Matts car is a very very nice car indeed, but difficult to say a value as every one is individual, but as an example my sapphire is Nouveux Red, k reg, all original panels, air con, leather, stage 1, and I would say to get the same car, same condition (waxoil underneath) would cost me around £7000. Some may say more, some may say less.
Marc the sapphire registrar would be able to give a current figure for valuation for Matt, I would say it is more than I value mine at, but not up on sapphire values.

Sorry I wrote a lot, couldn't stop blooming typing
