Gave these guys a call, i was impressed, he sounds like he knows his stuff.
Their complete Detail includes,
Inside valet
Outside with engine steam clean, 1 stage machine polish, G-Techniq C1 and EXO sealant on body, wheels, and windows.
Looking into G-Techniq, seems it is a ceramic and lasts 2-3 years the same as Cquartz does. I checked with my friend up north who personally knows a detailer that specialises in Exotic cars (http://tinyurl.com/jb5ulxn) and he only uses G-Techniq products so it must be good.
Total price £250!! This seems much more reasonable, Their Facebook reviews are all positive aswell. They keep the car for a day and half and can collect and drop for additional £10.
I'll give them a try closer to summer and post up pics
FYI....looks like we might be getting some real cold temps and snow this month down here
Keen to know how you got on with these?
