@bot I believe you'll have an issue getting any relatively recent car after 10-15 years of driving to pass registration inspection if there's anything wrong with it (I guess there would be a slight leniency given to cars seen as "classic" ones).

At that stage, a mechanic is likely to going to quote several thousand dollars in repair costs and most people would then proceed to drive the car to a scrapyard and buy a new one, or get a slightly newer used one without major issues for not much more than the repair costs.
