Got the ISF back and the tip has been fixed so it's no longer in danger of falling off. The air con service is pretty extreme though. The chemical smell is stronger than when I have had it done on previous cars. Hopefully the musty smell is no more but as all I can smell is the disinfectant it may take a couple of days to ensure that it has been sorted. They even knocked some money off as I'm a Gold member. Cannot argue with that. They did a health check on the car and it's all good apart from the fact my rears are down to 3.5 mm. I thought they felt less grippy so it looks as if they might need replacing in a few months and it's a bit of a shame that Lexus replaced the fronts when I bought the car as it would give me an excuse to try out some new rubber on all 4.
It was nice to have the ISF back, I really miss it when I have to drive any other car. All in all, apart from the whole courtesy car issue I'm very pleased with Hedge End yet again. Great service.
