Many years ago, a colleague lent his company Astra to four students who were on the company undergraduate scheme. Never a good idea to lend your car to students - I should know, I was one of those company undergraduate students once and used to enjoy ragging the pool cars as often as possible. Anyway, the student driving the Astra did about five miles with the handbrake on. When they arrived back at the office, the smell was horrendous, both inside the car and out. My colleague was billed for the damage too which was severe and rather unfair. Whether he exacted a vicious revenge was never clear.
