Maybe the tools and knowledge will become more accessible to the backyard mechanic in 20 or 30 years Pre-internet there's no way I'd be able to maintain any car beyond a Model T, so that's certainly helped. OBD scanners are now very affordable and have allowed me to at least do some simple things on our modern family cars, like find which O2 sensor needs replacing, etc. It helped me specify what was wrong with the transmission on our old Odyssey and address the problem (though not entirely fix it). Most of the wear items (esp. brakes and suspension) are easily DIY-able on most modern cars.

Maybe our access to technology will improve sufficiently over the next couple decades that we'll be able to fix 997s in our garage. If you think about it, it's just a collection of parts and wires that were assembled, so they must be able to be disassembled.
