good reliable reasonable mechanic please

Julia from Henderson

kia ora lovely neighbours

sorry, probably been asked before - but I'm looking for recommendations for a good reliable reasonable mechanic please

prefer Henderson - but open to suggestions

I have a good friend of mine who recently bought a car from a car dealership in south auckland (trying to move back this way - so car is currently here, out west)

he JUST got it and the transmission has issues - Mazda I think - this is waaay outside my area of expertise - I think he has rights (since he bought it from a dealership...?) - (thankfully, usually it's a 'mate' - & he spends more money getting it fixed, than pay for the car itself, or what it's worth)

anyway - last I heard it was trying to get it fixed from some place - pay them up front ($400, $500)- then try to get money back from the dealership (?) - and/or - trade the FIXED car (paid for out of pocket) in for another one - PAYING THEM yet *more money* - (argh - what?)

also *MY* WoF has expired

have - been going to my mother's old mechanic other side of the city (was her car before she moved into a retirement community in Nelson) - but needed a new battery a few months ago and people were going - you paid HOW much? ($200ish - he said it was new, 3 year warranty - told paid far too much - should have been about $50 ~sigh!~ ) so looking for someone I can TRUST - who won't rip me off, either of us off - reliable, reasonable, trustworthy...

please & thank you!
