OK - The problem with IMPORTING a whole mass of mopeds - is that there are already loads here - they're cheap and unlike (say) the UK - Home maintaining is uncommon. After sales will matter.

To get them a plate (legally they need one) they'll have to pass an ITV inspection so all lights etc MUST BE "E" marked. And if unknown in the EEC(really I mean Spain) they'll need to be homologated by an entity like INTA before you'll get ITV inspection papers to allow registration. This could cost a fair bit.

That or each one will need a one-off set of papers. This will add a €1000 (approx) to unit costs.

A 16year old CAN ride a moped - but they still need a licence - and yes a lid is a legal requirement. I don't know what the rest of Spain is like - but here un-plated bikes ridden without lids were common - but they're REALLY CLAMPING DOWN. Points and even withdrawal of license for either offence - and fines that may not sound HIGH but depends how much you earn.

I've an old friend here in Madrid that tried to bring similar stuff in from Italy - flopped miserably. Genuine €uro bikes - but too pricey and high consumption. Also you'll need to get the scooter mags to help - A LOT of scooters are purchased based on their recommendations.

imo you'll need to sell A LOT.
