Arnoud,
I think the panel has pretty much concluded that this is NOT a real car, at least from the chassis and trim items. As it is now, it is not an 850TC and from all appearances it is not a 1000TC either.
No one has mentioned the drive train. If it has anything other than Girling 3 piston brakes (presuming it was upgraded to 1000TC spec) then it surely is not original. Does it have dropped spindles? What type of front suspension? Leaf Spring or independent? What kind of trailing arms, standard or pendolare?
How about gearbox? 4 speed or 5 speed? What is the final drive ratio? If it is 4.88, rest assured it is a clone.
If you get a look at the motor, check out if it has what appears to be an oil filter boss under the exhaust. If this has a bolt going through it, it is almost surely an 850 or 1000OT block. What kind of waterpump bolt pattern? etc etc
Having said all of that, if you want to go racing in the Coppa Mille, don't do it with an original car, as accidents do happen. Ask Reinhold Koster who t-boned a Mini with his REAL TCR. OUCH !!! But by all means do go racing, even if it is in a nice replica. I did it in 2001 and and again in 2004. May do it again in 2008/2009, as it is a REAL blast and the other competitors are genuinely nice people.
I recently sourced a very nice 1000TC clone for a customer in the USA and paid around 12,000 Euro for it. I also was able to find another car for Pantdino in Europe as well. I know of several very nice cars that are currently for sale, including a 850TC replica that is as close to a real one as you are EVER likely to get. This includes girling brakes, period remote oil filter, proper small radiator, Campy wheels (the correct ones) etc etc. Send me an email if you might be interested.
The last REAL TCR that sold went a few years ago for over 50,000 Euros. That means that 1000TCs, should bring around 30-35K Euros, or even more today. I know of one VERY fast Coppa Mille racer that is for sale for 40,000 Euros, and it is a clone. Then again it has won its division the last 2-3 years, so it has a history.
It is all about what you get for the buck. Caveat Emptor.
Good luck,
Paul Vanderheijden
