Thank you so much for putting me in my place.
Regretably, I do not have the time (or frankly the inclination) to endlessly surf this or other sites, for information, which should be available to people paying £20k+ for a car, as I have to work (quite hard) to fund said purchases.
As I have (frequently) said - what about customer service? I would remind any manufacturer/dealer (sales or service) without us, they do not have jobs.....................
As for factory produced kits, dammit, the sodding car has been in design and production for long enough, why can't you do your jobs properly?
I REALLY wish there was a suitable alternative, because I would love to tell them to "poke it".
