Debs,
Count me in with the MGA, whether to St S or to your friendly cafe. Personal preference is for a route without too much traffic - the dear old A's cooling system struggles enough at La Sarthe and if caught in a traffic jam becomes a masterclass in juggling the clutch, throttle and handbrake, to avoid having to come off the throttle entirely and stalling through fuel vaporisation, which then takes 10 minutes plus to re-start.
Bill - you are such a gentleman..........
MG Mark
