I kinda worry some about all of the techy gadgetry in the new cars especially the luxury or semi-luxury ones where they keep trying to outdo each other. Had a recall on my Audi A5 to replace some potentially faulty pre-heater. Didn't even know what this was. It's an electronic thingie that gives you warm air heat fast so you don't have to wait for the coolant to heat up. In 46 years of car ownership I've never had a major engine or transmission issue, just annoying little stuff or stuff that just ages out like a water pump or fuel pump etc. In all of the those years it was manuals and I never even had a clutch done. Everything recently, say the last ten years, has been electronic accessory stuff.
Worst unreliable POS award: 1968 MGB*
Most reliable for 100k plus: Tie, 1988 Honda Accord, 2004 Audi A4. The Honda motor was still like a sewing machine but the body had nearly disintegrated from rust. Donated it to charity.
* Also most missed and nostalgic for.
