The Sonic LTZ is a comfortable compact with good MPG and handy extra features (e.g., MyLink, touch screen LCD, backup camera) and a surprisingly roomy trunk. I'm able to haul much more than I would've thought based on the car's appearance, especially when the back seats are folded down. I also appreciate the styling and ease with which I can get up to speed on the highway and up hill.
I would recommend this car to anyone that has a true love for the sport car experience. Having 400 hp in the l99 give you plenty to have some serious driving. Being placed on the zeta frame i have yet to have the car feel overwhelmed by the power and seems firm to the road. The brembro brake package also is very smooth and stops very quickly. The interrior staying gives you room for 2 people comfortably and the option for 2 more uncomfortably, however it can be done.
This car has been the worst vehicle I've ever owned. I've had to have it towed multiple times because of engine issues, fluid leaking etc.. Currently the vehicle is being worked on to repair the same engine issues it had a year and a half ago. There are MULTIPLE known issues with the 2009 Traverse with there being a GM warranty in place to cover those issues even though the car is so old. Luckily I got the extended warranty when I purchased the vehicle and that has covered non known issues but I've still had to pay a $100 deductible each time. Est. the warranty company has paid more than $10k in repairs on this car since 2015. The 09 GMC Acadia is the sister of the Traverse and has the same issues. I would avoid this car like the plague.
