I was bought a 'Sensational Six' experience ticket for Silverstone.
Could pick one of 6 driving experiences to do. I chose to drive a Pug GTi6 round the track. On the same session as me were the Ferarris and Caterhams so I got to watch what each one was like.
Think the ticket cost my Nan about £150 and yes it was fun, but it wasn't really what I expected, they were more interested in trying to teach apexs and stuff on the track when all I really wanted to do was rag the nuts off it.
Lasted about 2 hours in total I guess, and think the instructor lost his voice from shouting at me so much
