The secret with cars that have seven year warranty is to sell/trade them after six.
the cars are at worst OK, and are improving.
they're cheap to buy new, and are generally reliable(far better than any European marque)
routine maintenance is cheap
They're not worth much when the warranty runs out, but you'll still have lost less than an expensive car with better residuals. And those don't have 7 year warranties, so you hit the costs sooner
So you have the usual two choices: keep it until it needs an expensive repair, or trade it in for another. Your own preferences for expenditure and knowledge of how stuff lasts for you will make the decision.
Hyundai/Kia(which are very closely related) parts do cost a bit more than you would expect for the cheaper end of the market, but anyone who has priced Mitsubishi or Honda parts will laugh at you if describe them as
expensive.I'd be looking at any of the small to medium cars first, if I was going to buy a
new car. Cars are tools, and all of the pretentious marketing wank from the long established names is an expensive and tedious cost I could do without.
