You underestimate the enthusiasts. I just recently bought a refurbished “distance system” computer (aka cruise control ecu) for my 89 325i. I have, on order, an original head unit with blue tooth retrofitted.
Electronics won’t be the Achilles heel of old cars. Gasoline will be. But make no mistake. Old electric vehicles with their max 10-year life span of battery banks won’t enjoy the life of a classic either.
