it is 100% true that even a faulty system doing nitro will make the tire hold it's air better than regular air. and from my experience, that is a huge part of why people want it. the other aspect, all i know is that the tires get hooked up, purged, then the system puts in what i would assume is nitrogen (unless the tanks are filled falsely, which a dealer can't be held accountable for nor would i understand why they would bother going through with it)... i didn't see how the tires were done with that video, so i'm not sure if its a similar system... his test was not scientific by any means, but i do appreciate his findings.
the etching thing... i don't like it, but even so, it does offer something... to say it doesn't is like me saying insurance offers zero value, just because i don't use it. here is the spiel... etched cars have a $4000, 3yr replacement benefit if the vehicle is stolen and not recovered (on top of insurance payout). also, they have a plan that pays your deductible, up to 2500, for any repairs to a recovered stolen vehicle that needs repairs.
sure i don't plan on using it, but i don't plan on having my car stolen either...
at least it makes some dealers admin fees actually include something rather than paperwork.
and (yet)again, it all comes down to the fee charged. if it was free... my god, not to take it is pretty silly... if it is 1000, taking it would be ridiculous. so somewhere in the middle (closer to the free hopefully!) is where you want to be.
i love how i become the bad guy to rrocket for stating factual things and trying to explain how it works... the names he calls me would be akin to me telling the world people with long hair kick puppies... it's fact!!! i've seen a guy do it! and since you have long hair and are here now (doesn't matter that you seem like a decent, non puppy kicker) you are the worst puppy kicker in the world!
