I'm in two minds about this, I like that fact that my old morgan has 100 year old suspension, but I think if I was lashing out on a new one I'd be happy if it had a more up to date system (I have already felt the need to tweak the existing with adjustable shocks and newer springs). I really dont feel the need for ABS and I suspect that airbags in a trad with a wooden frame is a bit pointless
Conversely, I would only buy a citroen if it had hydro-pneumatic suspension.
