I think I need to wear my hip waders with all over the top commentary being thrown around by the seller without regard to the facts of this car - and there are several facts that are in question.
E9 windows are a known weak spot. It would be a good thing if they had been upgraded as described below.
The blocked off line below the expansion tank that
@sfdon saw ... Regardless of leaking or not - is NOT confidence inspiring.
There have been several cars here (and elsewhere) that have had work done by Oldenzaal Classics. They do decent work. They are not perfect though – some cars have been completed to a higher standard than others. Case in point here - there is no documentation on the body during restoration and paint. That and the missing shadow/crease line missing on this car (or at least it appears to be).
Also - the transmission..... With all the effort (I presume) that was put into this car - the installation of a 5-speed trans would be expected...
I'm not going to be the bad cop (at least not yet) on the auction. Will see where it goes... I might chime in there though and put a plug in for the forum here. LOL
