Viajar translated into spanish is Travel.
For which you have the spanish name for travel.biz
The domain would be evaluated at low XXX due to the extensions ability to sell at this time despite looking at past reports for domain sales -- the .NET and .TV had sold in the XX,XXX range in 2007-2008.
If I appraised Viajar.com for Industry Level -- despite it's potential being in the XXX,XXX range at 22,000$ The .biz would carry over still at possible mid XXX to low X,XXX.
You could post it for high X,XXX -- and see if an end user will come along. And in which case, I wish you all the best!
