I like Suffolk Cars but I have to say I always wondered how they got away with it.
By that do you mean got away with making replicas of an 80 year old Jaguar model ?
The replica business has been a thriving industry for decades and I'm not aware of many, if any, companies being stopped from making "copies" of long discontinued models. Indeed Lynx, who make a high quality replica have only recently brought the business back to the UK. Realm and several others are still advertising C Type replicas and there seems to be little change in the rest of the market.
There are several companies that build toolroom replicas of interesting cars including Bugatti, Bentley and of course Jaguar racing models. Links below.
The one car that does surprise me is the AC Cobra replica. AC were still making cars while the replica industry was churning out copies of their product. Allegedly more that 60,000 to date.
