Yep, they don't built anything like that anymore. I've already had to replace the door hinges on my Silverado at barely over 100k miles. I just did the pins and bushings on the Marquis 5 years ago at 230k miles, or year 32. MASSIVE differences in quality anywhere you look between the two. Thing is still running the ORIGINAL in-tank fuel pump at 290k+ miles, year 36! Impressive to say the least, especially considering I had forgotten to change the fuel filter the first 10 years we owned the car. Thing was plugged nearly solid, yet didn't damage the pump at all. AMAZING!!
I've never traded anything in either. That Silverado was the first new vehicle I've ever bought in my life, outside of motorcycles, dirt bikes, and ATVs. After that experience, and what I have to fix on newer stuff every day, that will be the last new vehicle I ever buy.
My next "new" vehicle will have a build date prior to 1973, and I'll build it myself the way I want it.
