Hi, so today I just got a call from the mechanic abt my car. My car is a 1990 Mazda MX-5, 401000km (body), 167000 km (engine), manual. I dropped it off last Tuesday for a major service + transmission oil change. They called me yesterday, and they said that the car’s radiator was leaking and it could be an additional $500+(aud) now I got a call today and they said that it’s gonna be around $1800(aud) total. Is it normal to get charged $1800(aud) for a major service + trans oil change + new radiator? It’s a mechanic shop not dealership btw. TIA
