A friend of mine drives a police Hyw Patrol vehicle. In training, if there are 5 cars in a pack, 4 new and 1 old, Which one do you check. The old one. Reason being in police training, is the idea that if you have an old car, you have less money, all the more chance to steal or owe fines and be driving without a licence. So they endorse train to pick on the poor. The theory may be close to correct in some ways. though how dare they have this as a part of police training.
