“I spent over a year going from mechanic to mechanic, Mercedes included, burning money. I had to come from Lisbon to Porto, to Master David's workshop, to get my problem found and solved.

Where BMW failed, AM Auto solved it.
The driver of it all
Mestre Davidand his team.
AM Auto is David Monteiro's multi-brand workshop on Rua Central in Valongo. Customers call him the master: the mechanic you go to when the dealer gave up.
He takes the car for a drive, plugs in the diagnostic machine and explains the fault in plain words. Then you get a list, item by item, and you choose. Many customers met the workshop through its YouTube videos, where every repair is shown and explained.
The queue of cars at the door says the rest: an honest garage has no need to invent work.
- KM01German carsMercedes, BMW, VW and Audi are daily work. Every brand is welcome.
- KM02The list, then youAn itemised quote before any work. Nothing extra without your yes.
- KM03Explained and cleanRepairs shown and explained, cars handed back clean.
