In Escazu we already have a place that attends the 24 hours the 365 days of the year for the maintenance of our vehicles,Car wash, waxed, oil change, arrangement or alignment and tire treading, basic mechanics.
In my case, I have taken the car to wash, they have done a very good job, also several times I have taken to fix some tires. And the service was satisfactory
The most practical, for my taste, has been that one can go at any time, like today pn Easter Thursday and they accept credit cards.
Locate in Escazu Centro from the Municipalidad de Escazu 150 mts west just infront pf Importadora Monge next to l Banco de Costa Rica.
