I agree that it's maybe worth a punt at £10 k to improve over time, but It wont cost a lot to get someone that knows to have a look.

Do they have a different chassis? (looks the same to me) --Quote

Don't know really, but I would guess they kept upgrading everything.

The Beaufighter of that era seems to handle the best because of the uprated springs and dampers.

I have a 411 and 603 and Beaufighter on the drive and you can feel the evolution and refinement. I had a ride in a Blenheim 4 today and I can assure you that the refinement continued to get a LOT better. Felt as good as my old Mercedes S600 and starting and running on LPG !!

A chassis is only part of a big equation. -- I also have a 1995 London Taxi that looks identical to a 1959 one --- it isn't !! but same chassis :-)
