For servicing a foreign car in Portugal there are official dealerships for most car makes throughout Portugal.
They are rather more spread out geographically than you will be used too and they don’t usually carry a large range of spare parts. So will probably/definitely have to order what you need. Usually from a distribution hub in Spain (beware of August when they will close for a month)There may also be an issue if you have the latest model of vehicle that it may not have been launched in Portugal yet making spare parts harder to locate.
Servicing a foreign car in Portugal
Independent mechanics are everywhere. Surviving upon their reputations for good quality work and low prices. They will normally offer you the option of fitting second hand/recovered parts instead of ordering new.
For example a friend recently had the catalyst converter fail on his Mercedes. The cost of replacing it in the UK dealership would have meant him considering selling the car.
Here his local mechanic cut open the exhaust, replaced the catalyst and welded the exhaust closed again. Cost 120 Euros!
We also know of several part-time residents who have their foreign cars serviced here instead of their home countries because the mechanics are high quality, low-priced and return the car to their home free of charge. Most mechanics will work from 9am until 8pm.
