You wish to own a Porsche and are looking around for "cheapest car maintenance place for this vehicle or good mechanic but don't charge so much for services"! Porsche is among the very costly cars. To own and maintain it, you need to have a lot of 500 riyal notes sticking out of your pocket,and you don't know what to do with them. You also need a big heart to meet its demands.
Porsche owners don't go about looking for cheap garages or mechanics.
