Im a huge fan of governments staying out of free markets, but I've gotta disagree with the above.
I could sell a new car with ZERO warranty, with the most rubbish parts that break after a week.
Sure, customers will EVENTUALLY put me out of business once the bad press spreads, but what about the hundreds, or thousands of people that forked out for a new car that lasted a few months???
They just get screwed.
Warranty stipulations can be just as bad. In AUS, you can service your car at any registered mechanic and keep your warranty. Imagine a 10 year warranty, but you need a mandatory dealer service every 6 months which costs you $1k each time.
No. Mandatory gov't warranties are good. They protect consumers and keep shady companies to a minimum.
