The only trouble with the comparison on cars is: they have gone way up in price. I'd guess a "family car" today is 10K more than 20 years ago. Is a 95% furnace lots more than a 92% furnace in 1992? No, probably LESS! And we wonder why they breakdown, are full of 3rd world country components or in the case of some products, made in Mexico altogether. People don't mind spending the big bucks on new cars but when you tell a guy with a 3 series in his garage that his 30 year old 60% furnace ought to be replaced, he screams like a stuck pig.
