    • I switched to Chevrolet from a Honda CRV

      By Markedu on Friday, August 16, 2019

      5.0
      This is one impressive car. I purchased the Chevrolet Blazer with 6 cylinder engine. It has everything I want. Great acceleration, Great styling, Quiet engine, Well equiped, I really like the turn signals in the mirrors, push button start, blind spot monitoring, cross traffic monitoring, Continental Tires, and easy pairing of cell phone. I did not get AWD or GPS. There is nothing, I would change and for the price, a great deal to boot. You won't be disappointed.…

    • Best one of the ones we tested

      By Paul46 on Wednesday, September 23, 2020

      5.0
      We bought our new 2LT Blazer after testing the Toyota Highlander, Subaru Forester and Outback. The Highlander was hard to get in and out of and the road noise was terrible in this vehicle. The Subaru's were judged to be too small and hard to get in and out of. I am an amputee on my left leg and getting in and out without folding myself up is a priority. Our new Blazer has the 3.6L V-6 and the power is amazing. It moves down the road with great authority over everything else we drove. It also gets respectable gas mileage at an average of 24 mpg. It is very quiet at highway speeds, absorbs the road with a very smooth feel. There just isn't anything to dislike about this vehicle. It will seat 5 full sized adults with ease and has loads of storage space in the back.…

    • Her car and She loves It - lets me drive on longer

      By Scout II on Thursday, June 20, 2019

      5.0
      Have driven 4x4s since the 70s - owned Scout Rallye II, various pre-chrysler jeeps, Yukons and Tahoes, and even a Sierra. This vehicle drives more like her 2009 Acura TL than an SUV. Replaced a one year old Acura RDX Advance that we never liked the way it rode, drove, handled, and had uncomfortable seating (unless you are skinny, 5'4, and under 120 pounds, which I am not. Have had the Blazer about a month, no mechanical issues, fun to drive, good vision, and acceptable fuel economy - not broken in yet, but slightly exceeding the 25 MPG highway. Wife loves the vehicle, it is hers (I drive a Yukon) - first time in years she wants to drive rather than ride. Looks like a great choice and a winner for Chevrolet.…
