Happened to see the 156 in the gumtree ad below (not mine I was there for another reason). Its very straight with good wheels and tyres, no interior. The motor apparently starts and runs fine but there is some sort of problem with the gearbox. The owner wants it gone and is quite negotiable on price. If it is not used in some way soon it will be sent to the crusher. The wheels and motor are probably worth something. Contact Stuart directly as per the ad.
