Seen this today on one of their cars driving around Dumfries. They are all over the UK, not just Dumfries.
But its a cracking price for 10 block of lessons.
It was on the back of the car where I saw it, but I dont see any mention on the website itself, so maybe quote that you saw it on the car when booking. Im sure it was a Peugeot 207/307 it was on the back of.
Hope it helps someone.
