One of Carousel's pair of Plaxton Primos, 752 (YX07HPJ), was painted in County Rider colours. It was new to Central Connect in Birmingham. It is seen leaving Wycombe Railway Station in May 2012 doing an unexpected turn on the Chesham route 4.
 
The Primos were ousted by a pair of Alexander Dennis Enviro200s, one red, one green, transferred from Thames Travel. Enviro 502 (OU57FGV) is seen shortly after deployment in Frogmoor in September 2014.
