The only 'extended warranty' worth anything is an OEM one. Aftermarket warranty companies make a ton of jack and really provide marginal coverage anyway.
Why don't they make non interference engines? Broke or skipped the gears on two old stretched out timing belts both thankfully were non interference. Timing belt replacement on certain cars can be a little extensive, of course you should also replace the water pump at the same time imo.
Yep totally agree, if you do the numbers most total aftermarket warranty costs would cover the cost of a fairly extensive repair,
I agree that most engines today are interference engines, however I don't agree that it's planned obsolesce. It's impossible to design an engine with a higher compression ratio and have noninterference. Just change your timing belt on time.
So are tighter tolerances the reasoning behind using water like viscosity oils these days? Steel timing chains eventually stretch also overtime, I hope some manufacturers still put an idler/tensioning pulley on interference engines? Also a freind of mine claims on the newer baby Duramax engines on 1/2 tons the whole engine needs to be pulled to replace timing and oil pump belt, OEM specs I believe put replacement under 100k miles. It would be amazing if engineers and bean counters worked on cars previously lol. I dislike I have to pull my fender liner to replace my fuel filter on my 6.6 Duramax.
Cool rc engine. Had a wankel in one of my old Evinrude snowmobiles. Interesting write up on it, despite me drifting like a UP snow drift. It definitely weighed a lot like article says and rode like a bulldozer, stripped out the plug threads on it due to engine design couldn't put a helicoil in it. Unfortunately ended up parting it out and scrapping the rest over 30 yrs ago.

It wasn't just the Wankel which had problems back then though. The plugs were fat with about 3 threads before bottoming out. When changing them in a hot engine- a common occurance with the earlier sleds- it was easy to strip them out.Cool rc engine. Had a wankel in one of my old Evinrude snowmobiles.

Even the OEM warranties are a rip off. I recently saw that even warranties that aren't scams have a 50% to 75% profit margin. That means that odds are you will only get back 25% to 50% of your cost.
You either lease a Mercedes or sell before the warranty expires.
The dealership we bought my wife's SUV from offers a lifetime powertrain warranty on every car they sell. It's one of their sales gimmicks. Her SUV was 2 1/2 years old when we bought it with about 17k miles.
HP don't mean a lot to me, MPG does.
That applies if you don't have any warrantable issues. Today's vehicles are so complex that any warranty (extended) is better than none. OEM's aren't nearly as bad as the 3rd party ones, by a long shot.
