Yeah. Vauxhall/Opel has always been my go-to example here. Their cars excel at nothing. They’re not especially stylish. Not the fastest or nicest to drive. Not unusually efficient. Not particularly reliable or guaranteed for a long period. By no means the cheapest. They don’t even achieve a sweet spot of averageness across all these things. Yet people have somehow carried on buying them over decades.
Jeremey Clarkson called the Astra "the most boring car ever made". I loved both of mine - they always got me and my stuff where I needed to be, and were easy to fix.
The last one, a 2007 model that has now moved on to my younger sibling, might be the last "simple" car.
