Hi guys, thanks again for all the enthusiasm and kind words! The car is a real gem, and I am totally in love!
@ Scooby: The roof is carbon fibre reinforced plastic, there is no sun roof.
@ artofzen: Yes, the allows are a charcoal grey, sort-of graphite colour.
@ R.P.M.: To be honest, I'm going to try and use the M3 as my daily driver. No point in owning this car and keeping it bottled-up all day!

For any stints that will be too crowded or dodgy, I'll probably use the Getz. I think the Mondy will go on the market very soon.
