Car appreciation... the aesthetics, the engineering, etc

Don't go very often, but travelling from Scotland to Bristol a few times a year. Is there a free park and ride? Or is it a case of quietly dumping it on some suburban street just outside the zone and then riding/getting a bus into city? Up here they are putting ULEZ zones into the centres, buses and taxi companies get a 2 to 5 year amnesty to catch up with cleaner vehicles.
