Consider who is selling this car, and who either owned it previously or is having the Pomona seller sell it for him. Who else could it possibly be in Pomona other than the infamous Ben Miller of CSi and 2002ad fame? I know the car did belong to david baker in Oroville, CA and ben miller is one of his best (only?) friends. Baker lied and cheated me on a car purchase which was one of the most blatant cases in my experience of someone misrepresenting a car. Baker owned the car, and now Miller is selling it. Miller is also one of the people who has cheated, lied and stolen from me. All in the line of E9 business.
Is the car worth 180k, maybe, maybe not. Is Cary Ida's Alpina CSL worth the $500k that they are asking for it, probably not. Bonifide sales of CSLs have not exceeded $153 as far as I know, the one at Christies in London in 2006 sold to some Saudi greedbag for that amount. It was not even a series 2 bat, but rather a fairly well used Bat series 1 (2275 car).
Any car is worth what someone will pay for it, nothing less, nothing more. This particular car's ownership puts its history in serious doubt, I would trust nothing I heard and maybe half of what I could see. If anyone on this board or who reads this board can afford that much for a CSL, look further for a better bargain. I know of a very, very nice series 2 bat that sold a couple of years ago in Europe for a bit over 50k euros. Perhaps if anyone else was selling it I would concur with the pricing, since it is within the realm of current reality for very rare BMW's. Will someone who spends a million plus on a rare Ferrari or Maserati be interested in this car, I doubt it. Its not that rare and its not that collectable/desirable. Nobody loves CSLs more than I, having owned 8 of them including two batmobiles, but I do know they do not attract the really big dollar collectors.....yet. Will they ever? Who knows?
To anyone seriously interested in this car, BE CAREFUL, the seller puts it in seriously questionable territory. Find someone to inspect it who knows the cars, like Peter Sliskovich in CA. And good luck.
