Hey my son works at BMW he is on the X6 line as the inspector for the line. They make and sell every X6 loaded and M also for about $136.000. They can't make enough of them. They are coming out with some new models I will have to ask what they are that start out over $200,000. They will have reclining heated and cooled back seats that have foot rests like your TV model. The back doors will be wider than the front, Boss in back driver in front. I think 32" monitors in back. People with money would think nothing of that would brag to their buddies at the bar what they spent for it.
BTW it costs around $15,000 t0 $16,000 to build and X6 depending on the options. The rich get richer.
PS never buy anything from Perkins.
