I'm always curious to know how much performance a car might lose as the miles and years pile on. So I decided to treat myself to a Racebox. Firstly for some track timing and importantly to put some 'real world' figures against any cars I'm lucky enough to drive. So, what better way to start than with my 25 year old M3. I wanted to know how it was still performing. On track the modern kit can often run rings around it. I wanted to know if that's because of drop in performance or, perhaps, my ability😉😂 I also wanted to know if old stool German engineering was 'that good!'
