Here is a brief article from 2014 and looks like the same car.
http://germancarsforsaleblog.com/wag...6-2-8-touring/ https://www.alpina-automobiles.com/e...-3-series-e36/ It sold for 14K in 2014 according to germancarblog and it's listed in alpina archives.
Think of it as a 2.8 M52 that makes 240 hp via custom pistions and camshafts and tuning. It did not get a displacement increase so how it drives with our crappy fuel that is a question for buyer.
