I've got the 2010 LTZ I-4 and I echo much of what was said in the review. I just got back from a 2000+ mile road trip to Florida and the LTZ was almost flawless. Ride and drive were extremely comfortable. IMO the I4 engine has plenty of power for the majority of folks out there. I would only buy the V6 if I needed it for towing. The car is also surprisingly quiet. Definitely quieter than any of the competition that I drove when shopping for a new car.
I saw 25mpg on the highway but, most of the time, I was driving 80mph. I also has two small dogs, luggage, Christmas packages, and my wife in the car. I was also using E-10 fuel for the entire trip (sucks 10% off your mileage right there). In ECO mode, I do think the transmission holds top gear more than I would like, so I simply turn it off for city driving. I had it on for highway driving and had no issues.
Two other things I should praise are XM radio and OnStar. I have been dismissive of these two products in the past but now I'm addicted to Blue Collar Radio. I've already bought a subscription. OnStar also performed beautifully as I used it to navigate to my destination. I used it to find a hotel in New Orleans, find my Mom's house in Florida (first time I had been there) and to find several other destinations. OnStar was DEAD ON every time.
I do have some very minor gripes.
1. iPod/iphone integration works but is clumsy. If you connect an iPhone 3G or 3GS, you get an error asking you to switch the phone into Airplane Mode. You can safely hit NO and continue running normally. The car then plays your songs in ALPHABETICAL order instead of track order. Lastly, there should be an option for you to connect your iPhone but not automatically have music playback. Right now there isn't an option for that. Most of the time, I'm just hooking up my phone to recharge. The actual controls are done through the menu/tuner knob on the radio. I thought it was cumbersome. That knob is also too far from the driver for regular use and should have a redundant control on the steering wheel.
2. The power lift gate button on the rear gate should be illuminated. It is invisible in the dark. This is more of a suggestion than a gripe.
3. I was surprised to see that GM is very limited on the available accessories for the Equinox. For instance, there is no cargo mat available from GM. Fortunately HuskyLiner is selling one now. I could have used one for my trip...
All in all, I am extremely please with my purchase. The LTZ trim is a lot more luxurious than you might think. IMO it is a vastly better value than the entry level Caddy SRX, which only has Leatherette.
