I've been expecting this one to come up. This is the car that was sourced (from an auction) and imported for a customer by the self-styled 'GTR Heritage Centre' here in the UK some years back. At that point it was fitted with overfenders (the rears were mounted on the wrong sides of the car...) and it was soon featured in a UK magazine article. At that point it was being described as - and I quote - "immaculate".
Some time later the owner sent it down to Fourways Engineering, and I was asked to inspect, authenticate and make a report. Even from metres away I could tell that there was a lot wrong with the car. A closer look shocked me and, after some interior panels had been removed, the truth started to become apparent...
The car had been bodged up in Japan - by a non-specialist - just to put it through the auction, and virtually the whole rear half of the car was made out of sections cut out of a '75-up North American market model. The quality of workmanship was unbelievably bad. Some of the worst I've ever seen. Just gobsmackingly poor and - in some cases - bizarre.
The car has come a LONG way since then (it went through a huge body restoration) and it was massively improved, but I still think the Mecum auction estimate is way high. Personally I would value the car at around half of their low estimate. I just hope any new owner does their due diligence on the history, condition and detail originality of the car.
