American made. Less expensive to repair. We'll appointed. Comfortable. Built to last.

We are pleased with the SLE features. Compared to our Equinox LT, it was missing heated front seats, a powered driver’s seat and lift gate. However, the 3rd row was an upgrade that we needed. The V-6 engine is also strong. We sacrificed gas mileage, but upgraded in cabin space, so it was a win for us.

The SLT meets all of my requirements and has some features that I didnt even know I was getting. A bit smaller than the Buick Enclave we traded in but we were looking to downsize a bit (we are retired and didnt need the full size car). The one draw back is the ugly front plate holder but its required in TX so you are just stuck with it.
