I was once scrapped a honda civic and it had coilovers & alloys on, which i was going to keep, so the way i done it was.
I put the car on a ramp and un-tigthtend the alloys & coilovers nuts/bolts, then winched the car on back of recovery truck, jacked up with trolly jack and removed the wheels, then put planks of wood so the car resting on the woods, then took out coilovers and tied the car down. Job Done.
But the reovery truck was my own.
