🔧 What Mechanics Don't Tell You
- Labour is the real variable. The same repair can cost 30-50% more at a dealer than an independent, purely on labour rate. Always ask for a written quote with labour hours itemised — if they won't itemise, walk away.
- Aftermarket parts are fine for most jobs. OEM (original equipment manufacturer) parts carry a 30-60% premium. For non-safety-critical parts (pads, rotors, filters), reputable aftermarket brands (Bosch, Brembo, Sachs) perform identically for a fraction of the price.
- Get 3 quotes — the spread is real. We've seen the same job quoted from $400 to $1,800 across Brisbane shops. The cheapest quote is not always the best, but neither is the most expensive.
- If they won't itemise, walk away. A reputable mechanic will break down the quote into parts cost + labour hours + markup. If they give you a single round number, get a second opinion.
