Plus one for the annual test, peace of mind that someone else can have. look over it and identify any wear that comes in gradually that you don't notice driving the car until it's too late. Insurance is another issue, prove it was maintained properly in the event of a claim? MOT history is a good starting point. Interestingly, although the Stratos replica is registered as a Historic Vehicle the mere fact that it's a kit (or a Radically Altered Vehicle) means MOT tests forever....
