Far better than I expected! They got the history wrong, bubbles and micros did not date from Suez 1956 and the Fiat 500 did not set the ball rolling. By accident or design they did perpetrate the "no reverse gear" myth with the Trojan and Messerschmitt both being pushed backwards, but I admit that this might have been because the Trojan was being awkward and it was quicker to push the KR than use its reverse.
On the plus side they did show the fun and strongly argued the point about the huge size of modern cars and moden congestion NEEDING a re-birth of micro cars which are acceptable to most drivers.
