Most of the descriptions are only snippets of information, but they ring true regardless - e.g. if you aren't tuned for 93 instead of 87, running 93 will not help you or your engine. Unless your idea of helping your engine is knocking and forcing the ECU to retard or advance timing, you sadist.
Second, concerning nitrogen-filled tires: why in the name of all that's logically sound would anyone be duped into believing that pumping nitrogen would be beneficial? Think back to grade school, kiddies; atmospheric "air" is almost 80% nitrogen. Even if there was an upside to switching, it'd be insignificant at best. On a good day. If the nitrogen was blessed by the Pope. Twice. Add to that the facts that you have to pay to get the nitrogen, plus they over-inflated your tires, and it's simply moronic. I understand what they're doing, that's the scam = they over-inflate your tires so less of the rubber contacts the tarmac, therefore lower rolling resistance and some increase in MPG. But then, without that proper contact, you lose grip and prematurely wear your tires. I'll stay old school on this one, thanks.
Third - wait, what? Do I really need to say anything about "magic fuel-saving" items? If you're foolish enough to believe those ads and not do any research, you deserved to be ripped off. The same goes for cure-alls that promise to "make your car like new." Next.
That brings me to the final snippet, the only one I find myself disagreeing with: wheels, stereo systems, and other electronics. The MSN author, James Tate, takes a wholly pragmatic and not completely unfathomable position - leave your car alone, spending money on silly things like that will not help the resale value of your car.
And that opinion is fine. If you're 70 and drive a Camry to bingo in Ft. Lauderdale. And you don't want to know anything about your car except to "stick it in D and go." What about normal car guys, though? If you want to spend $900 on a set of these beauties (Enkei RPF1's) with tires,
what's wrong with that? Lighter wheels and better rubber than stock is always a good thing if you care about handling. Which you should, since it's just a bit important to have a good-handling car.
A better head unit and set of speakers is always an upgrade too, especially if you're an audiophile like myself.
Sure, these things might not add to the resale value of a car, but honestly, if you're worried so much about resale value, you either own the wrong car (e.g. a new Accord sedan) or you're missing the enjoyment of driving.
If you don't like that, you might be in the wrong hobby.
