Hi, I joined yesterday. Thanks to Sneaky Pete and jbanks15 for your speedy advice. I have 2007 SLK R171 280 that's been customised and is on 19" black alloys with low profile tyres , which (surprisingly) still offer a good ride and can handle bumps. It sounds great with a custom exhaust and is fun to drive especially on winding lanes. I can fit my surfboard in it with the roof down - it fits snugly on the passenger side.
