I'm not being nostalgic, I have no misconceptions of what cars were like in the 50's and 60's. I'm speaking from experience and specifically to statements like they rusted out after 2-3 years and were all junk after 5 years. We're not talking about Chrysler "K" cars from the 70's!
How many of you "know it all's", fathers, brothers or uncles were automotive mechanics in the 50's or 60's? How many of you apprenticed as an automotive mechanic or worked in a garage in the late 60's or 70's? I see one.
Well I worked on these cars off and on from the mid the 60's into the 80's. I remember that cork gaskets would dry and become brittle over time so valve covers and oil pan gasket did leak. So too did the rubber O ring seals on Corvair push rod tubes. So what? That doesn't translate to junk after only five years. (Please refrain from making stupid Corvair jokes, thank you very much.) Enough of these "junkers" were still on the road 15 and 20 years after they left the assembly line to help pay for my hobies. Do not mistake "failure to maintain" a vehicle for "designed in" five year self destruction.
There are many things that I do not miss about the older cars. However, new cars come with their own head aches. Got a problem with you BMW Mini's transmission? Sorry, we can't pull it apart to see what's wrong because it's a sealed unit. We'll have to order you a whole new transmission. And don't get me started on trying to diagnose electrical problems. Sorry sir we can't find the problem. Your vehicle has 5 separate CPU's. An engine management module, a drivetrain module, an accessories module a safety module and a communications module so they can all talk to each other. But, we're not sure which one is screwed up.
If you're going to start throwing statics around then please get them right. Automotive research firm Polk's most recent study shows that the average light vehicle in operation in the US was indeed 11.4 years old. However, it did NOT state these average light vehicles were registered to the SAME owner for that entire time period. In fact in other published reports the average new car owner keeps a new vehicle for only 4 years. Even though that sales surveys indicate that the average new owner claim's to be looking to keep a new car for at least six years. Imagine, consumers lying on surveys, who'da thunk it?
