All the ones in excess of $100k are individual cars in unique colours such as Dakar yellow for example. The prices quoted are the MSRP prices and the vehicles are loaded right up including competition package, gloss black trim pieces and the like. Teh asking price includes full retail MSRP for the base car, individual colour and all optional packages and DCT. As with anything else, the asking price is merely the MSRP and is subject to negotitaion (I would hope).
As has been pointed out, a "base" M3 is still available in Calgary or Edmonton in and around $70K....
