I was slightly annoyed that they let me book an appointment for 2 days time, then immediately cancelled and offered a booking in 3 weeks. However, this was over the Xmas period and better than other local garages. One the actually day I was really happy with their communication and customer service. I will definitely be using again and recommending. I loved the clear pricing structure
