I have mixed feelings about JD Power's ratings. Buick? WTF? I've owned a GM product before. It was a very problematic. Most reliable vehicle thus far for me was a 1987 Isuzu Trooper II (2-door). Absolutely, bullet proof at 200k miles. This was the reason, I sought to once again return to Japanese cars with my Mazda purchase.
But back to the ratings. Having owned a VW, near the bottom the ratings, I would never buy another one again, ever. Terrible reliability. Nice interior, and fun to drive, but an absolute money pit. Same thing with Land Rover. Even worse reliability than a VW. My father owns an LR. I would NEVER buy one. And most recently, I had an '07 Jeep Wrangler. Also near the bottom of the list. That thing was crap. I lemon lawed the damn thing and I got my money back. Need I say more.
So there you have it, Jeep, Land Rover, and VW all near the bottom of the list and I have had horrible experiences with all of them. And I will never buy any of them again. I see Mazda is also near the bottom. I can already say that the materials, buying experience, and car features on my 3 are excellent. So far, so good with mine (knock on wood). I guess only time will tell.
