Greg discusses wether you should buy a new or used car using the bathtub curve as the best example to prove it. The bathtub curve (or the break-in period) is an engineering graph that illustrates the life cycle of any manufactured product. In this video Greg explains how it pertains to cars and whether you should buy a new car or a used car. Discussed are early failure rate, the stable phase and the end of life phase which make up the bathtub curve. Richard Deming introduced the concept that Toyota perfected. The Toyota Production System is discussed and how the TPS is the best quality control system in manufacturing.

Never heard of the bath tub curve before, I liked the simple explanation of product life cycle/span— and I do love my 2 Toyota’s @ 195,000 mile Toyota’s and still running and working excellent
Good job on the left side of chart, but didn't say when it is too late to buy before it falls apart after stable period.
How old used car should i look in India?
Diesel is prime choice
That's right, I still drive a 2008 yaris sedan, thinking to upgrade to a 2015 mazda 6 estate but I'm still satisfied with the yaris
السلام عليكم
It’s 4:20 somewhere….
This all seems right. When I first saw the title and the curve, I assumed he was going to talk about the value of a car over it's lifetime. They start out expensive to buy, then there is a period when they remain as low as they will ever be and then if they are special in any way they begin to increase in value. I suppose 60s-70s muscle cars would be a good example of this. Of course run of the mill milk chasers just continue to decrease in value until they are junk. I suppose my mind goes towards the cars that can begin a rise in value because those are the cars I love. And I make money while driving them.
Greg, i know this video is old so I hope you see my comment, but at what mileage do you consider the sweet spot to really kick in? Does it depend on the brand and model?
It's the thing I find hardest to gauge when buying a used car. Does it have too many miles/KM's and it's almost at that end of life stage, or is it only just entering it's prime? Am I paying too much money for something that might fail in 12 months time?
Thanks.
4:20 Lol
Is a 2014 Highlander XLE with 180K miles a good buy? It’s one-owner, highway miles, dealer-maintained, all dealer service records, clean CarFax, in excellent condition. (Is 180K miles too much, even for this car?) They’re asking $18K, and that sounds kinda high. What’s a realistic price?
Does this still apply? They're selling used car for more than they cost new 5 years ago
Why did a clock appear over the speaker’s right shoulder, 4:20 o’clock – then vanish 27 seconds into the video?
It's interisting how you tried to apply this RCM concept to cars but there are some other important things to consider, for instance, there are 5 fail patterns you didnt mention, not all car's component fails like the bathtub and every one has a different time basis, it is, not all bathtub are synced so some components wear out sooner and others later, foremore many of them respond more increasing the random fail probability in time… That's why the warranty is as short as is.
When I bought my new 2003 Toyota Tacoma the sweet spot began the day I drove it off the dealer's lot. After 19 years of daily use I've only replaced the radiator, water pump, sensor, and some belts. I love Toyota's sweet spot!
Next, talk about the failure rate of markers.
Interestingly, for tires, it is totally possible to make a tire that can last 100 thousand miles (in normal regular usage), but there is no interest for the industry to produce something that will not give enough profit, so they keep them in the interval of 50k to 75k. The compost for car tires is made to last as much as the other competitors, no more, no less.
Toyota didn't stretch the end of life phase out, they issued recalls for mass frame failures. Undoubtedly, the engine and transmission will likely be running still when the frame or unibody is rotted out. Do they make a good product? Usually, but the Toyota reliability pedestal can be much shorter than everyone believes.
Well done with the information, first time I've ever seen car channel go through something like this. Thank you for your time..
Toyota be like what curve?
what a brilliant video this is, I'm IN.
So, a 1 year old car should be more expensive than a new one.
i like the theory and it makes sense but i cannot imagine right now where to get that graph for a Corolla for instance. I mean , no money-making corporation would give the consumer that graph , because then nobody buys new cars :)) that's not completely true of course but sales would be hindered . and of course the graph itself is no absolute data because it's more of a collection of spikes that are being averaged . and it's always a problem of perspective , changing the clutch assembly at 140k km would be , for some, outrageous , and for others normal … . same goes for the prices . so a guide in this manner would be handy from the car maker 🙂
SO TRUE!!
nice vid ty
How about vw and ford?
