Hi, having spent ages choosing a car suitable for touring the UK, I'm looking for an recent XC40 - does anyone know if its possible to retrofit any of the tech. features? I have in mind the following example: I might see a 2018 XC40 on sale at a garage near me and decide its the right car for me except I'd ideally like the lane assist feature and the car in question is great in many other ways - price, colour, condition, etc.etc. except for the lane assist - is it possible for Volvo - or a third party, of course! to add it in afterwards?
