You may also need the rear fog lights re-wiring to comply with Spanish regulations.
Presumably, as an HGV driver you’re familiar with driving a RHD vehicle in Europe?
The problem is that once you’ve done the re-registration of a UK car, along with the necessary lights conversion and paid the import taxes, you’ll end-up with a car that’s not very desireable on the resale market. That means that you need to run it into the ground before replacing it to get your moneies worth. As it gets older then getting replacement parts may be difficult, especially if there RHD specific such as steering components. If you are going to do this then choose a vehicle that’s popular in Spain, so scrap cars will be easier to come by. Remember that it’s illegal for a UK resident to drive a foreign registered vehicle in the UK, so taking the car back to the UK for a major repai will mean getting it ferried both ways on a transporter (maybe no time an issue if you have friends in the transport game).
Personally, I prefer to drive a LHD vehicle in Spain, and I like my vehicle to be fairly reliable so that when I arrive back in Spain I can be fairly confident that it will start and run well. For that reason, running an old RHD Car into the ground isn’t the way I chose to go.
