Many thanks to all who have responded - your thoughts and suggestions certainly have given me something to work with. I'll probably take the car to Revolutions in Perth (nearest Morgan Dealer) and ask them to review the steering geometry / set up / parts etc. The steering wheel is a Moto Lita - wooden Rimmed wheel and fairly large so definitely not an aftermarket sporty job. I did drive a Morgan at Revolutions before deciding to buy one however on a test drive you don't really get to throw the car around. There are plenty of people racing them and doing auto tests etc so I am guessing a more agile feel must be possible!
