Yeah, will need to drain all the fluids e.g. petrol, oil, water, coolant. Will also need to spray the whole of the underside very thouroughly (correct spelling?) with powerhose, to get rid of the oil and grime, as well as cleaning the wheels properly. can all be done in a couple of hours though.
You could just remove the engine altogether leaving just the chassis and body. can fill the bonnet with plants!
There would be a lot of workand a lot of sparks when dismantling. COuld we do it in that small space. Porbably, but need to make sure we can before we shove a van in their. Either that, or if we ever have to move to a different venue then we should rebuild the engine a drive it through the front of the building.
