The reply from BMW is VERY odd.
For BMW to say there was not a Touring ‘crossover model’ is misleading. The model 73 Touring, just like the sedans, had the updated front panel & grills and the fake wood cluster surround and ‘crosshair’ gauges.
What is generally stated as a 2002tii Touring in the faq ‘Production Numbers’ page, is the ‘facelift’ model built from 08/73 thru’ 04/74 and known as model 73. 724 of them were manufactured.
Your car, 3425XXX, is known as a model 71 E6 Touring tii. It is, therefore, one of 5059 built between 04/71 & 07/73. While it may have a 2002tii script on the rear and noted as 2002 in the sales paperwork etc., it is still a model 71 Touring tii.
Info that I have, would suggest BMW started to put the 2002 script badge on the rear of Tourings in June, or July, 1973. So, a few model 71 Touring tiis left the factory with a 2002tii badge on the rear, BUT, they were still model 71 E6 Tourings.
FWIW:
3424180, 3424275, 3424680 all have 2000tii scripts on the rear.
3424974, 3425059 have 2002tii scripts on the rear.
All the above would have been built late June into July 1973 and are model 71 Touring Tiis.
You posted earlier that the “Production Numbers” in the faq was in error…..

Now, realizing that BMW 2002 Touring tiis are actually the ‘facelift models’ model 73 only. The above reference in regard to Tourings is not incorrect.
