  Best SUV in Canada - 2008 Mercedes-Benz GL-Class
  By Marco Khan - February 20 - 1:43 pm

  Excellent drive and you get the feeling of a solid vehicle. Excellent interior and exterior finishing. Mercedes have thought of all the details and have done many improvements in the GL. We had two ML 320 before and now find the GL much more driver friendly.

  2008 gl450 - 2008 Mercedes-Benz GL-Class
  By DAWN - January 31 - 6:30 am

  I am a previous LX470 owner and I have to say there really is no SUV that compares to this car for comfort and the ride and the third row seating. I cant wait to get in my car every day and drive it! Although the nav doesnt compare to Lexus ease of use and the DVD is in a weird location for usage. I also did not realize that the non-leather seats are a bit sticky in the heat due to the fact of no ac in them. The ac works great and the stereo is better than my Lexus. The windshield wiper controls are hidden and hard to see. I kept hitting the cruise control for the first month, now I am used to it. I have never had a Mercedes so all the controls take some getting used to.

  In Love with my GL 320 CDI - 2008 Mercedes-Benz GL-Class
  By pollyspop - August 25 - 9:00 am

  Traded from a Yukon XL. I pull a 4000 lb boat and wanted to go greener. 23 mpg my first 2000 miles compared to 15 mpg with the Yukon. And all this Luxury! I bought the Premium 1 pkg, Trailer Hitch (which is very unabtrusive),19" wheel pkg,I-Pod Plug, Side rails and chrome fog lights. Power and Acceleration are Not an issue with this vehicle. I know there will be a larger diesel engine soon...I will not need it. I find the Ultra Low Sulfur fuel everywhere.

  Gl 450 Major problems - 2008 Mercedes-Benz GL-Class
  By tnance - June 18 - 12:20 pm

  I purchased the Gl 450 4.7 Ltr about 1 year ago. It has spent over 2.5-3 months at the dealership while attempting to fix electronic problems. While driving the vehicle it would surge and then the warning lights would start lighting up like Christmas. The lights warned of the following failures ABS, Air bags to many to name they were all on. Then a big red box on the led would state drive to the dealership immediatly without shifting gears, how you do that in an automatic Im still trying to figure out. We live in an isolated state with few roads and long distances between help. My faith in the Gl is gone! Hope no one else has experienced this. It still looks nice parked in my garage.

  Best MB Yet - 2008 Mercedes-Benz GL-Class
  By Austin - January 24 - 7:53 pm

  The 2008 GL320 CDI is the best MB Ive yet owned, out of 4 different models. It is my go-to car for all short errands and long trips. It is very comfortable, super quiet, safe, has excellent pickup (we live in the hills), has great visability and gets good mileage - averaging 20 mpg city / hwy. Also, in my mind, diesels are a better environmental solution than hybrids because of the battery production and disposal issue. Few vehicles with this weight have the same ability to pass other vehicles when you are going 40 mph or faster. We have towed horses and hardly notice the additional weight except for more downshifting and fuel consumption.

  Loving it - 2008 Mercedes-Benz GL-Class
  By ADNoVa - October 30 - 5:43 pm

  Picked up the GL 320 about two weeks ago and couldnt be happier. Got rid of an XC 90 over size and quality issues. Compared to the GL, the XC90 feels absolutely asthmatic. Love the power and torque of the diesel. Its a little noisy in first gear but its no worse than the whine and groan of the Volvo. I drove every full size (not giant size) SUV and nothing in this class compares to the GL in terms of space and comfort. Getting 23 mpg blended around town is a happy bonus. Drove the V8. Love the sound and its faster overall, but around town with kids, not worth the fuel economy trade off.

  This GL is awesome. It rides so smooth the transmission is flawless. I really do feel like Im in a G500 jet or something. Great acceleration when needed.

  2013 has been a Very Bad Year. - 2008 Mercedes-Benz GL-Class
  By cc57 - August 27 - 9:49 pm

  Purchased new, our 2008 GL320 has been eating us out of house and home in 2013. Since it hit 80,000 miles, weve had multiple, expensive repairs with each being about $1,500 to $1,800. In this order, left front air strut replaced, turbocharger replaced, fuel pump replaced, right front air strut and air compensator valve replaced. Both the turbo and fuel pump failures left us stranded and required towing it to the dealer. Unfortunately, we did not purchase the extended warranty as I thought that a diesel would be bulletproof. Obviously, I was very wrong.

  GL 320 vs. Buick Enclave - 2008 Mercedes-Benz GL-Class
  By rrtker - June 20 - 1:36 pm

  I purchased an Acrtic White GL320 on 10/31/07. I love the vehicle and overall the fuel economy of the diesel is meeting my expectations. Now that I own both the MB and an 08 Enclave I can honestly say that GM has a winner on its hands. The MB certainly has some enticing things including the diesel offering, a firmer ride, etc. But dollar for dollar the Buick is pretty hard to beat. If they would simply upgrade the quality of some of their plastics and the fuel economy, I would be hard pressed to choose one over the other.

  The perfect SUV - 2008 Mercedes-Benz GL-Class
  By Andy - January 19 - 1:40 pm

  This is my wife/family car, we owned this GL320 CDI for more than a year and I love this SUV. Every time I drive it, I enjoy the ride. I drive a 335 convertible, but the handling, feeling and cornering of this truck is incredible. I strongly recommend this vehicle for big families, and if its diesel more.
