I do have the tyre pressures slightly higher than standard, but not quite as high as 36 PSI.

Suppose that I have owned 340's for around 20 years, needed virtually no spares, brake pads seem almost everlasting.

The sills have had an extra injection of wax by me.

When I said heavy body, I was comparing with my Classic Mini that has an engine not that much smaller than a 1.4, it's a bored out 1275.

I was expecting the car to be bad in snow, having been used to Minis, 1100's and Metros, however as you say the 50:50 weight distribution makes the 340 quite good.

yes the 1.7 was a much more modern engine design and certainly more economical than the B14 and went very well (105 mph) despite only 8 bhp more than the B14 . It was a detuned Renault unit ...

you mentioned brake pads , when I said my two had never needed parts brake pads were changed of course BUT both have their original rear shoes and cylinders ..and the 1988 still has Its original Volvo coolant .
