I'm going to disagree with Joshty - fora are groups of people sharing their opinions & experiences - the more sharing the better. I've found some fora focus on repairs & maintenance (
www.suzuki-forums.com), some place greater emphasis on modifications (this one), others on general usage (
www.auszookers.com) - personally, I'm a member of a dozen or so automotive forums (mostly Suzuki, along with a few Mitsubishi - in addition to my GV, I have a Pajero iO) and visit half of them several times a day (I moderate two).
There's not that much information around on the 06+ GVs - I suspect because they're too new (and cost too much) for most of us to be beating on them, but there may also be a perception that they are "soft roaders", with monocoque chassis and all independent suspension. I did consider one before buying the 98GV I have now, and to be quite honest, the more I learn about them, the happier I am that I bought the older model.
I am particularly troubled by the front suspension design, which in my opinion is better suited to a FWD sedan than an SUV - in fact, it's very similar to that found on the Mitsubishi Lancer and also a number of Toyotas - the rear bush on the control arm has a vertical orientation so that the up/downl movement of the wheel twists the rubber at two points, causing it to tear in a relatively short timeframe - I've seen the arms changed on a number of stock (unlifted) vehicles that have never left the pavement (admittedly our roads are not that good) - lift the vehicle and it aggravates the problem - at least one Australian firm offers an aftermarket polyurethane bush that supposedly fixes the problem, but my suspicion is that the poly bush will also have a short life span (I believe it has a sliding motion in some areas, and once grit gets in there - and it will, given the location of the bush - wear will be the end result)
There's not that much stuff available - OME have springs and a front bar, they have been promising shocks & struts for some time now, I don't know of any lockers available.
