Depends on your chassis number. I assume it will be mclaren london who are doing the upgrade given your location? They had the most cars to go through in the UK so i guess the london/south east area cars are going to take the longest. Bought my car in sep and had the upgrade done at the end of november with a fairly early build chassis.I picked mine up in September as well was promised January but I am waiting for a pick up date. I agree on the black exhaust covers how much do they ask for them ?
