I bought this car second hand (2005 CV Sports), having just sold my old car - a 2009 Hyundai Getz. I previously owned a Kluger CVX model in 2008-09, which I originally sold due to high fuel prices, however after a year and a half of the Getz, I missed the versatility.
I absolutely love it. I have not experienced the automatic transmission woes that others are talking about, although I do agree that the shift up and down is 'different' to other autos, and occasionally mine has brief moments when it has to think about what gear to go in. My CVX seemed to have it more than my current one, and I test drove another Kluger CVX about 3 years ago that seemed to suffer from it quite badly (going up a hill while turning right).
I have either bought one of the good ones, or have adjusted my driving style so it is not as bad. I tend to drive leisurely and never seem to fang it. I find that when I am in a rush, the transmission isn't as smooth, although I still don't think it is unreasonable. I also use PULP fuel, which may make a difference.
I really like the fit and finish of the Kluger; everything seems solid, and it's nice to hear a thud when closing the doors. The cloth seats are also much better than the leather; my old CVX had cracking in the driver's leather and this is another reason why I was happy with the CV Sports (with cloth trim). The only downside with cloth is that it marks easily, however I am sure a good clean would remove most marks.
The engine is great -- it's such a nice sound when you accelerate from lights, and surprisingly fast for the size. I also get a lot of looks, so the exterior appearance is definitely not outdated.
I highly recommend the Kluger -- the only thing I suggest is a very thorough test drive to ensure you're not buying one with transmission problems. Also use PULP, and see if that helps.
