Before the lock down, my car needed new tyres. The advice I received was to buy the tyres online and have a local company fit them. Instead I went to my local company (family business) and they quoted the same price for the same tyres as I could get online but their price included fitting. Deal struck, tyres ordered and fitted the next day. Then I was told to stop by anytime and they will check the pressures and adjust for free as part of the service. I appreciate this is a smart way to keep my custom but they have my business and my recommendation for as long as I'm around.
It would be great to hear other experiences of good value and service in Portugal.
