I want you to feel totally comfortable buying a second hand minibus from us. We pride ourselves in being a trusted advisor to many schools and colleges and I want you to feel the same as if it was a brand new vehicle we were delivering. We have known your vehicle from new, when we delivered it, until now.

A unique feature with buying from the Castle Group is that your vehicle will have had a professional safety inspection covering 52 points at least twice a year regardless of the mileage and this is in addition to its annual MOT and regular servicing. You can therefore feel confident that you are buying from a reputable organisation.
