My wife, brother and I did the 1.5 hour Vintage tour, it was incredible. What made our experience awesome was our tour guide, Ana.
My brother and I speak Portuguese but my wife doesn't speak it well enough to understand what was being said. Ana's English is impeccable and she was able to answer all of the questions we had regarding Porto's rich history. She is very knowledgeable about Portugal's history and current events.
Ana easily and safely navigated the city, which is no small feat. Driving in Porto can be challenging especially when the tour took us through very busy streets and pedestrian only areas. The electric replica Model T is ideal for this dual purpose and can reach speeds up to 35km/h.
