"I dread replacing my 25 year old Volvo with a current model. Too much technology for technology's sake."
The battery on my early 1990s BMW 535 lasted...12 years. It was quite the surprise at the dealership when they told me it was a factory original.
A friend with a recent X5 had to surf YouTube to find out how to log into his car's firmware to tell it that he was changing the battery.
YMMV. Your patience will vary too.
