Thanks David π
Sadly, no track day, but I am not in a hurry to take it there anyway, especially, as you say, the tyres don't last long at the best of times! To be fair, since it does handle so amazingly well, I do tend to throw it around corners quite a bit, so it isn't that much of a surprise that the tyres don't last that long.
I do intend to use the main dealers for service, so thanks for the warning and I will watch out. Having said that, it is always good to know of a decent independent for anything that isn't service or warranty related, so I will keep Ray Northway in mind should I require their services. I found out that Porsche Reading charge Β£291 per hour for their labour!
