I see your point.
As much as the January show has its downsides, I've likely been more often disappointed by the February one.
Nearly every year I go looking forward to seeing some specific model and find myself disappointed as it's not there. This has been from Japanese and European manufacturers equally.
This season I want to have a close look (as in I MIGHT WANT TO BUY ONE) at the BMW R1250RS, Honda Transalp, Husqvarna Norden, KTM 890, Moto Guzzi V85TT and most of all the Moto Guzzi Mandello. I expect that one or two of those will not be present.
At the same time, I'm more likely to go to the February show than the January one. In spite of the cost of parking and lack of vintage bikes, local riding clubs and beer nuts.
