Moving to Portugal with my 2016 Escalade platinum

I have 3 vehicles I’m taking with me to Portugal Mercedes S63, my 95 SL, and my Escalade.

Everyone is telling me I should sell my Escalade since the closest Cadillac dealership are in Spain and they don’t have Escalade’s and I most likely won’t be able to get it serviced. Even though it’s a 2016, I only have 22,000 miles.

Does anyone know of auto shops in Portugal that might be able to service it? Or are the dealerships in Spain capable of servicing it?

I don’t like range rovers, or bmw, and really want to keep my Escalade, I’m not bothered by high fuel prices.

Any advice?
