I agree with Deman77

And there are other factors:-

Pump Price difference that may grow, ad blue another forgotten cost although may be small.
Surcharging for Diesel's driving into Cities over the coming years.
Price depreciation may grow wider, certainly will not get closer.
Servicing costs later on down the line.
Another stat though not to sure on it, but was posted by Car Mechanics Trade, Diesel's are 30% more likely to break down.

I find it hypercritical that Manufacturer's are pushing Diesel's so hard offering huge discounts just to shift what they know is a doomed and to be banned engine, wether if it is right or wrong.

It is a tough choice for sure, but many do not look at the long term picture, 3 years in todays car market is a very long time.

To the OP the engine does loosen up after a few 1000's miles, will help fuel consumption a little, and look at polestar maybe that will increase it and give other benefits.
