Wouldn’t it be possible to download the software file from this car (subject to the owner’s permission) and apply it to another? Is that massively oversimplifying it? Are there hardware changes too?
I like some of the current resto mod creations, whether they be Porsche, Lancia or Renault etc. Analogue in feel yet more useable everyday......BUT, my god they are expensive. Do you remember the Lancia Integrale resto mod they had on top gear? Lovely thing but ludicrously expensive and when...
Surely it would only be a 19 registered car if it was sold and stored and not registered, as the last single clutch cars were the Strads in 15. They will ultimately need to make those parts available though as the EU mandates minimum support for 10 years after sale. I guess it is out of stock...
Are you keeping the trickle charger inside the boot? If so, I would remove it to the outside and stick it in a dri box or similar. You can get a ctek extension lead from Amazon.
