I find the NPMP not bad, there are many hidden cost if you do outside.
Change auto/cvt transmission oil, other oil if need to top up they will do. Change brake pad, wiper, tire balancing, air-con gas, filters, spark plug. Got whatever problem just tell them. The only thing is the fastflo engine oil not sure how good is it compared to other branded ones, can't find info on it. Their prices seems not that bad compared to other AD. Considering to take up another NPMP when servicing is due. Going to reach 60k soon so need to change cvt oil.
