VW re registered my car

So I had this happen to me and just throwing it out there to see what others think.

So bought a Cupra tavascan 251 in a cupra dealership about 20th sept, few dates later received logbook and taxed the car. In mid October got a speeding ticket from Garda send back the form few days later got a letter from the garda saying no further action needed no and disregard previous notice. Hurray such a jammy fecker 👌Then last week received a call from Cupra salesperson saying that Volkswagen group had received a speeding ticket for my car (same speed same place same reg) and could they have my licence details. I refused and asked why vw had received a speeding ticket for my car, it turns out that vw had re-registered my car in their name ( along with 5-6 others) and only became aware of this when the speeding ticket was issued to them.Cupra ireland rang yesterday to say sorry,  I asked them how they could register my car without informing me or my permission no answer.I asked them how that could be done and does it breach GDPR as effectively they stole ownership of my car Without a signature of sale or bill off sale. My understanding is also that if my car is not in my name legally then my insurance is null and void.The car was in registered in vws name for 3-4 weeks before they discovered the issue. Thank god I was speeding 😉I appreciate getting a call from them saying sorry but thought they might have offered something (new car 😉 just joking) like free service.Is it reasonable to look for something like this or should I let it go and chalk it up to a learning moment?Cheers
