I Think I Don't Want These Computers in Cars Anymore

My rant is less about computers in cars and more about piss poor quality in general. My 91 year old mother was headed to an appointment earlier this week in her 2012 Chevy Equinox when it **** the bed on a very busy road. Thing just died outright on her, so she had it towed to the repair shop, and was told the timing chain tensioner crapped out, engine is finished. It has about 110k miles on it, 2.4 Ecotec pos. Sad part is the car is still in reasonably good condition, but not worth repairing as the cost would be more than it's worth. What really bothers me is that she and her dimwitted husband think that's ok, the car served them well. What?! It's only got 110k on it! What's worse is the dimwit just spent $7500.00 on a clapped out 2000 Mustang convertible with 150k miles because, "oh, I bought it from a buddy and he said it was a good car". ******* thing is a rusty pile of crap, and I am a Mustang guy!
So now she's all stressed out about having to buy another car and the cost, etc.
