Don't even think about it. Most towns have a weekly market and if you happen to miss it go into one of the large supermarkets, for a great display of fruit & vegetables. You'll be pleasantly surprised by the selection, size and quality.

Spain has mangoes, too. But even if it didn't, most countries have laws against bringing in fresh produce (due to concern about accidentally spreading pests or diseases that could damage agriculture). If you try this anyway, make sure you announce the fruit to the customs department upon arrival. They'll probably confiscate the fruit, but that's better than paying a fine (if caught) or trashing Spain's fruit industry (if not caught).

... Just checking you know that we have mangoes in Spain ? ( And Electricity, roads etc...)

We do have them here, in fact I bought some last week, they were beauties! so juicy, just under ripe, lovely!

Why? They are on sale here too.

Umm.... I don't see why not.
