ITS striking yellow paintwork means it has become a recognisable feature on Colchester’s nightlife scene.
Inside, its wipe clean seats may have been at the receiving end of alcohol-unduced vomit and have provided much-need respite for sore dancing feet.
But Colchester’s original SOS Bus - which has provided crucial medical support to revellers - has sat virtually unused since it became unreliable and was replaced.
Owners the Open Road charity are now hoping to flog the 23-year-old bus for £15,000.
Despite its former lively lifestyle, the charity says the bus still in full working order and only needs some minor repairs and patch ups.
Wayne Powell, SOS Bus co-ordinator, said: “We have had interest from a few people, such as event medical companies, and a similar type of project as the SOS Bus here, but in Glasgow “The bus has been un-used for the last 18 months, apart from an eight-week pilot project in Ipswich but has been kept securely in a lock up “The bus is in workable and good condition and viewings can be made on arrangement.”
The diesel-fuelled vehicle was donated to the charity in 2007 and was converted into the SOS Bus, suitable for mobile medical use.
The main area inside it has clean wipe seating down both sides, two plasma screen TVs on the walls, and a sink and preparation area while the back has been converted into a self-contained medical room.
This includes a medical couch and storage cupboards.
Outside the bus, there is a built-in TV for viewing outdoors, as well as speakers and an electronic canopy that runs down the length of the vehicle.
The bus’s replacement cost £60,000 and was put on Colchester’s streets in autumn 2012.
It was paid for by Colchester Council.
