Buy any sort of car built before 1996 (the year OBDII became required) that you like, and spend some money fixing it up. You'll spend way less than on a new or recently made used car, and it will have virtually no electronics in it. At best, it will have a controller for fuel injectors. Between 1996 and ~mid 00s, you had some of that stuff but really not that much. If you're willing to tolerate an ECM and some jankiness with factory radios controlling the security alarm and nonsense like that then you can avoid all the modern garbage. Unfortunately governments are beginning to mandate some of those gimmicks. Even if a car company wanted to make a car that is just a car, without a rear camera or stop assist it likely wouldn't be able to be imported to anywhere in Europe or anglophone north america.
