Am I missing something here? I used to own a '99 M3 (last year of the e36) and while a fantastic car, e36 M3's were never really much of a limited production vehicle, except perhaps the sedan versions, which were only produced during the '97 model year and the lightweight model produced only in '95. Not like the original e30 which was a homologation special producing just enough vehicles to be allowed in racing. The '95's, like the example in this thread were popular with those who liked to mod their cars engine performance due to the OBD I system enabling less restrictiions than OBD II. '95's also had a slightly smaller engine (3.0L vs 3.2L) and slightly less torque (225 vs 236) than following years.
But, perhaps the most negative aspect of the e36 M3, is that US versions got a significantly tamer motor as compared to the the euro models, which put out in excess of 300bhp. But, I believe it was only around 286bhp or so on the '95 euro models. US M3's were more like a stroked version of your run of the mill 325 and 328's.
With that said, I don't see how or why a '95 M3 in exceptional condition with low miles could command anything near the mid-thirties for a 20 year old car, considering a brand new '95 back then could be had for less than 40g's. Fast and great handling cars for sure, but collector's items not so much. 20k tops IMO.
