Hi I used Car registrations based in Las Alcaraz in Murcia.
Took car in went shopping came back 4 hours later to have an ITV pass and headlights re aligned rather then replaced.
Plates and all relevant paper work arrived in post 3 days later.
Hyundai 7 seater cost €1385 plus headlight alignment think it was €180 per.
Had a quote for my 2010 jag XF €1535 plus lights will do next year
Will swap licence once residencia sorted
Hope this helps
