I Think I Don't Want These Computers in Cars Anymore
Pre-OBDII cars are much harder to diagnose. As the cars get newer, the self diagnostic gets more advanced.
Gotten a little bit ridiculous lately with the gagets, however saying you're better off with a carb car, meaning that you won't have to work on it at all is kinda funny honestly.
I know a family that drives a lot of miles, they had an 04 Accord with 435k that they bought new and never had an engine/transmission rebuild or replacement, they currently own an 07 Accord that's over 380k with the same. They just change the oil and if its really broken it gets fixed. Nevermind the just massive amounts of other Hondas/Toyotas and all brands of pickups in the 200k+ range let alone in the 300's. My friend has a 96 K2500 Chevy with 251k on it, original engine runs like a top - and it has a 5-speed we just put an input shaft in due to the roller pilot bearing failing. Real original otherwise. Even newer cars I see Rav4s and Camrys with or without Hybrid in the 400k range often.
If you are a mopar or no car guy then there aren't many models that are really known for high mileage. They've built a lot of subpar stuff the last 40 years.
Would be rare/near impossible to go this type of mileage in an A-body with a carb without an overhaul of the engine or transmission, let alone not rebuilding or messing with the carb.
Right now, and I know this is going to sound counter-intuitive to some, if you buy a new vehicle, buy a Toyota or Ford Hybrid with either company's 2.5 engine attached to it and you'll just sing past 200k so long as you change the oil. Watch a video about the "Transmission" that's there which can basically be better described as a torque splitting device than a CVT. For normal use they're keeping the fuel consumption low so you can enjoy your classic.
