Sorry........it's a BMW thread! BMW M3 CRT revealed - Autocar.co.uk Despite the whopping surcharge of £1000/kg weight saved in the new BMW M3 CRT I like the idea of carbon fibre reinforced plastic. Maybe I've missed the news threads, but I'm wish MB would use more new materials. Remember the days when family cars weighed 1000kg? For a modest consultancy fee I would propose deleting the sounding proofing to saving more weight. They could charge the customer even more then! It reminds me of my pet hate of carbon fibre interior trim!
