I purchased my Envista ST (Trax in essence save the more posh interior) and so far I am quite pleased. I traded a 2014 Lacrosse 3.6 producing ~320 hp. I loved the thrust of that engine but grew increasingly disenchanted with its fuel consumption. I always drove with one eye on the gas gauge which tampered my enjoyment of driving it. The large Buick was a superb car for wafting along the interstate but could acquit itself well on more demanding roads. It had great isolation, a well-integrated powertrain, and superb interior fit-and-finish. But I had to let her go to make way for something more efficient. The Envista has a very controlled ride (courtesy of its Watts-link rear-suspension), accurate steering, and a small engine that punches above its displacement to keep me happy on town roads and the highway. The engine emits a distinct "thrum" during acceleration that sounds rather sophisticated. The 3.6 in the Lacrosse was much quieter of course but this 1.2 is comparably smooth at idle and very nearly so during operation. Well done GM. The 6-spd. transmission operates inconspicuously and, taking full advantage of the broad torque output of the engine, feels more natural, I believe, than would a cvt. I have owned quite a number of V6 powered GM products over the years that I have always tuned when possible, but I have adapted quite well to this sedan-like cuv and I don't regret trading the Lacrosse. The Envista is a worthy addition to the Buick brand and I believe the ST trim is the one to get. The Avenir has a somewhat swankier interior but it shares the upgraded suspension with the ST as well as most of the tech. The base Preferred trim is no slouch either and is probably the best value. I strongly encourage anyone in the market for a smallish cuv to test drive either a Trax or Envista as the experience may shock and delight you.
