Thanks, clears up my issue finding the service sheet. Yes the handling is great. I had been looking at the Aston Martin just before I got the Merc but the livery I liked was out of stock. What I was thinking about was whether I could swap out the rims, or even the entire rear axle set and replace with something that holds 12mm tyres. The wheel well looks like it could take more without having tyres extend outwards of the body. I don't mind the upgrade work, just not sure where to start on the options.
