The mechanic who will be in charge of balancing and controlling the carbs was puzzled to see my new NGK coil - as he told me - 'upside down' (connectors below). He told me (and a good mate as well) that it was a wrong position and that he will change it next Thursday. However asking Google for 'Rover P5B engine bay' and having a close look on dozens of pictures featuring the coil, I noticed that a huge majority of them had also the coil upside down. Are the modern coils different from those older ones? What's the truth? Thanks.

The truth is you need to find a mechanic who knows what he's talking about!

Yes, your mechanic is full of it...
Besides the Rover, I have almost always owned and air-cooled Volkswagen and they made 21.5 million of them with the coil upside down from the factory.
Click in the image and you will see it works too.

The reason why the coil is upside down is to stop condensation travelling down into the HT and LT lead connections. Early oil filled coils leaked sometimes but the seals were quickly improved.

Thank you Phil My coil ref. is NGK U1079 and filled with oil. Hence if the orientation doesn't matter provided there's any leak and it works fine, I'll ask the mechanic to leave it as it is. If it ain't broken...
The main point for the mechanic will be NGK spark plugs, carbs, advance and idle and... back tyres because - believe it or not - while going at the garage my 2010 Dunlop NS rear tyre (the ones I'd not still swapped) had a puncture. A lovely young farmer who was following me flashed his headlights to warn me then gave me a hand swapping the spare wheel. He was truly delighted and admiring the simple, efficient and astute design of Rover stuff to swap a wheel!

Well any car gets punctures and more often than not if it has been driven on the tyre will scrap

I've got 2 Dunlop Sport Classic 185 80 15 the same that were fitted in the front a few months ago. It'll be done as well next Thursday. After all 14 year service for tyres it's time to retire! Mind that last December I made my 600 mls journey with two 24 year old Michelin on the front! The weather was rainy, roads sometimes muddy and often wet but nevertheless never ever the car slipped away at any moment even when reclining in roundabouts!
