Guaranteed to enjoy, I am in no doubt.
Incidentally, my own (minor so far, by comparison) experience of the MG4 on sharp and narrow hill-climbing in the lower Pyrénées is that the recommendation to use sport mode is scarcely necessary, as it belts up everything anyway with max torque from the off!
Actually, as an aside, your post gave me something of a surge of jealousy, as it reminded me that my first trip to the Alps, in a blistering summer of 1967, was also in an MG … a smashing black with red leather 1962 Mk1 Midget (6466 ND), that had been well-tweaked with Formula Junior ‘bits’. My very young girlfriend and wife-to-be came with me (bravely – in two senses of the word in those distant days!) and we headed through Alsace to Basle to Geneva, then south via friends in Briançon (the highest town in Europe), then, after a 15-kms skip into Italy (just to be able to say we did), we headed down to Saint-Raphaël on the Med, before travelling north up the Rhone valley, Burgundy and Champagne for home … and yes, there is another theme there – apart from MG!
It would be fun to replicate the trip – in a ‘modern “MG”’, but not sure if it would be quite as exciting these days, nor if I now have the stamina. If I were some years younger …
Looking forward though to hearing your own experience i.d.c. … have fun.
