I think emotion is a large part of this. There is a huge element of 'coming alive', experiencing driving for what it really is, in the raw. You are driving without the aid of technologies which somehow leave you numbed. This is fresh,stimulating, invigorating. It's like taking a challenging walk in the Dales with old friends you know well. You feel satisfied, healthy and in control of your destiny. Having just moved on to an 'armchair sports car' for health reasons, enjoy all you can while you can, as soon as you can.
