This very clean, very unoriginal example sold for $31,880 on April 30th, 2020. It proves that a well executed tribute car and a purposeful driver can still fetch enough money to make building such a car worthwhile. While it's unlikely the owner recouped his entire investment in the build, if he enjoyed the car, and the build process, then I would say he broke even and then some. The listing details an impressive investment in period go-fast parts, including an aggressive diff. and rare dogleg transmission, that rightly pushed the sale price up.

A little gem in Sahara. Proof that the 2002 market prizes preservation but won't pluck their hair out over numbers matching like some of their colleagues. A 2.0L engine snuck its way in under prior ownership, and that's to the good, mated to the featherweight construction of the 1600 it offers a speedy package. With a deftly restored interior and exterior, it was a bargain at $26,000 when it passed over the virtual block at BaT: https://bringatrailer.com/listing/1971-bmw-1602-6/ (P.S. behold the undercarriage shots - the definition of a California car)
