Like a few others I went for Gtechniq Crystal Serum Ultra, including the glass, wheels, and interior (all treated with the appropriate Gtechniq products). I'd highly recommend the product and the results were fantastic. My local detailer is UAS in Llanelli, they were great... https://l.facebook.com/...

Hi all,

I was a JLR employee for many years, my wife currently has a 2017 F Type P300 Coupe and Im running round in a 2019 XF Sportbrake 300 Sport... Very different cars sharing the same engine!

May I ask a related question... I also have a P300 Coupe and at 70-80 mph its stable enough, but taking it much above 90 and it starts to feel fidgety, at 100 -120 it is chattering, vibrating or something... it's not pleasant and doesn't feel at all safe or stable. I just need to sort out the proble...
