Even maestros have a bad day. That could explain the square-looking Zagato styling of the 412. But despite being launched during the blackest days of the ‘70s with a gigantic V8 engine, the 412 continued to sell for Bristol, even building up a modest waiting list. The quality was as deep rooted as ever, and the chassis was straight from the tried-and-tested 411, although the targa roof panel was a genuine innovation for the company. The 6.6-litre V8 was downsized to 5.9-litres in the late ‘70s, but the grunt remained intact.
