I wish to thank all who have taken time to offer advice. I recently drove a Defender that only had 10,000 klms on the clock. The clutch was controllable and I was comfortable. So my mind is made up. I will not be buying the one with the snatching clutch for fear of great expenditure. I hope to buy one that has only 10,000 on the lock if not new. I live in South Africa and the exchange rate makes new rather costly.
I knew my instinct from 50 years of driving ordinary cars had to be of value. Thank you all again.
Jim
