As a stag do thing/birthday present my dad bought me and my brother (best man) tickets to have an hour with Mercedes AMG on the track - that's 5-10 minutes instruction, then 50 minutes driving my pick of Mercedes AMG cars around a track with an instructor.
How much fun is this going to be?! The biggest engined thing I've driven before is a Jag X-type 2.2D - I get the feeling a 6.3 litre CLK AMG might be a little different...
