I have always got a courtesy car, as i need a car to get about and do the daily stuff and they kept the car for most of the day on every service, i ever had on the scheme for the last 9 years and with 3 different dealers. The only time i ain’t is when i popped in for a wiper or for the mot, but last time they needed to do a software update and they said it would take 3 hrs at least to do just the update and then rear brakes needed changing also, then they did mot… So if i have to wait until, they have a car available, then i wait.
