Hi everyone. I just joined this forum. I am most likely buying a new GLA 250 in Nov or Dec. I am not sure whether to get a 2019 or 2020. My question is... I test drove the 2020 yesterday, and it had a slowness and sputtering when starting up at traffic lights and changing speed. I thought it might be a gear shift issue and am wondering if this new car simply had a flaw. I should have said something to the salesman but he was very pushy (trying to get me to buy on the spot) so I said nothing to him. I drove a new 2019 about two months ago at a different dealership and it was totally perfect. Because of the experience yesterday, I am a little nervous about buying this car and I was super excited until yesterday. Any advice, ideas, etc. Thanks in advance.
