Bringing car from Barcelona to Malta, easiest way?

The easiest way is to sell everything and take a plane to Malta. Really, it would be easiest and (most probably) cheapest.

Also, you should consider that Malta has LHD (left-hand-drive) and Rent-A-Cars are relatively cheap, if you go to the local companies.

have you checked the import registration taxes for the vehicle etc

It is an old Tata Sumo from 1998. The question is that I want also to bring some personal belongings that although they are not very valuable I don't want to threw them.

I imagine the taxes on a 1998 car are not exceeding the cost of buying another similar car in good condition here in Malta.

I have read that Malta doesn't forbid cars with the steering wheel on the "wrong" side, although maybe is a bit risky.

valuation.vehicleregistration.gov.mt/motorVehicle.aspx have just gone through all these tricky little details and bought myself an older LHD car for just that purpose (1999 Vauxhall Elite, former diplomats car, as LHD cars are a rare species here in Germany). Anyway, the maltese "Online Taxameter" gave my car a value of 800€ (haha) and calculated on this basis some 1180 € import tax.

Posting a suitcase or 2 is another option. That's what my mum did from the UK. I don't know the costs but it must have been OK or she would not have bothered.

we flew from Gerona on Ryanair with two cases each and hand luggage total of 90kgs in weight so depending on size etc of items will be a lot cheaper and quicker doing it this way. Also Vueling fly from Barcelona to Malta again can get quite cheap flights.

The registration tax and other administration fees may not be very high for a car like yours (but you'll be surprised anyway ), but it adds to other cost like diesel, highway fees, ferry fees etc. Not to mention the time lost on travelling (in case you do not like to travel )
Then you have a LHD which can be quite annoying here, besides of driving, the access to car parks etc. is on the right side

Pallets dispatch or shipping in wooden boxes is often cheaper and more convenient than travelling with your own car !
