I have the same car but 6 speed manual and it will be quicker than the auto! Never really compared properly but I have driven an auto and it is different, more control over the rev range with the manual. However, 1st is crap, on the drag race you need a rolling start, but once it’s passed second then the power and speed does build and quick! I though about selling in a few times but not done it because just like you it does put a smile on the face when driving it. I call it cheap fun with all the thrills 😊
