2. Nissan's legal staff is EXTREMELY stubborn and persistent. Nineteen years ago, I bought a new 240SX that wouldn't pass the emissions test. (The dealer stickered it the first time but it never passed a test at the state inspection stations.) No matter how many times to the dealer, no matter how many parts they replaced, it never passed the test. Nissan even admitted that the car would never meet the required tests. Their "solution" was that I should bring the car to them and let them fraudulently sticker the car every year. Should have been a slam-dunk case for me -- an emissions related defect from the manufacturer. Should have been a very simple fix. But . . . eventually, it was lawyer vs. lawyer. I fought the thing for THREE YEARS to get them to make it right and they never did. After three years, I moved to a jurisdiction that didn't require emissions inspection. If I hadn't, I suspect I would STILL be fighting those guys.

And, only now, 19 years later, am I finally willing to look at buying another Nissan.

Never underestimate any company's willingness to tick you off for a dollar.
