It's the same car?
Could we list both together with the same name?
Are they different cars?

According to a comment made on one of them, Ebro bought Viasa, so they were named Ebro later.
I already regrouped Jeep-Viasa & VIASA Jeep, as I had that on my to-do list since some time ( ) but I think that Ebro Jeep should be kept separately (or under the Ebro make)

Ok, but it's possible to distinguish between both? There are any change?

no idea
