D302PEV is a Volvo B10M-46 with Plaxton Bustler single deck bodywork and was new to Harris Bus in October 1986, along with three sisters. When new they seated 38 though 302 currently has its luggage pen removed and is thus currently upseated to a seating capacity of 41.
The B10M is really a chassis thatís intended for coach bodying, and the Plaxton Bustler body is a modified version of its Paramount coach body - the combination is no surprise though when you learn that Harris Bus was created to operate all the local stage carriage work & contracts of sister company Harris Coaches following de-regulation of local bus services in 1986.
The bodywork is actually extremely rare, with only around 50 examples ever made. Ralphs Coaches of Longford had the biggest single fleet with 26 Bustler bodies on Ford chassis for contracts at Heathrow Airport - two of these are known to still exist in New Zealand; one as a caravan!! Fellow Essex independant (at that time) Hedingham also had at least one on a Leyland Leopard chassis. Note the coach chassis theme!!
D302PEV and its sisters were the first new vehicles for Harris Bus and formed part of the initial launch fleet for the company. 302 and its sisters initially operated primarily on Essex County Council contract routes 265 (Bulphan - Brentwood), 269 (Grays - Brentwood) and 372 (Grays to Orsett Hospital); though as with any bus company fleet, it would have worked any route the company operated. When it ended its days with Harris Bus at the end of 1996, it could usually be found on route 383 (Chadwell - Lakeside).
