Hi
We go to a trade fair in Madrid every other year (only every 2 years) called “Motortec” we supply tools so I am not sure if it is only the motor trade that are to go there - search for Motortec and see if you can go there as well. It is a good trade fair
There is also a large exhibition in Malaga that I have been to, although I forget the name of it now and that was all types of industries that were there and it was a good fun day out.
La Trocha in Co?n have a trade fair every year also and that happened over the weekend just gone, the place was heaving with people and seemed like a good place to be.
Hope that helps 😊
