I'm a car (and motorcycle) person...
I enjoy driving, not being distracted by smartphones. I love simplicity and reliability. I maintain our vehicles myself. We regularly use our 23 year old Chevy truck with 338k miles while our sports car is operated infrequently on good weather days.
Here's just some features and my comments:
- Technology like blind spot monitoring and catalyst exhaust control are good.
- Start/stop while slightly better for fuel economy under limited conditions, it can reduce the life of an engine.
- Direct injection while better for fuel economy causes carbon fouling of valves and intake ports which requires more maintenance. (Port injection is better for lower maintenance as it washes the valves with fuel and delays carbon build up.) Direct injection also requires high fuel pressure pumps which are more prone to failure.
- Engines now use a variety of fuel saving designs (e.g. variable valve timing) which, if not maintained, will cause premature engine wear and ultimately, failure.
- Oh, I just added this...don't buy a vehicle with CVT or continuously variable transmission. They have short lives. They are less expensive to manufacture and weigh less allowing manufacturers to improve fuel economy figures in their reported averages. Just. Don't. Buy. Them.
Poor vehicle maintenance is the primary cause of shortened vehicle life. Number one item to check at every other fueling is the oil level. Yes, check it OFTEN. Emission control designs such as PVC and EGR systems are causing engines to consume more oil due to lack of maintenance. When oil is being consumed it's telling you that something is wrong such as carbon fouling of oil control rings on pistons, a PVC system or EGR system is clogged, etc.
Example, I just cleaned the (minor) carbon fouling on our truck throttle body and checked the PVC system the other day. I do this about every 50k miles. It slightly improves the idle and off-idle operation of the engine.
