I do not necessarily disagree with his preference (I have a 3), but the article is garbage.
1 - The 3 looks better than the Y.
I can't really argue with that as it is totally subjective, but that is just 1 sentence out of 2 pages that make up the article.
2 - The Y has more cargo room, but no more 2nd row leg room. He doesn't care about cargo room, but he does care about 2nd row leg room.
As others have pointed out, the premise is just not true, the Y has 5 extra inches of 2nd row legroom. Plus with a higher seat your legs point more down than out, so the same leg requires less leg room. There is significantly more people space in the Y.
3 - "4.4-second sprint time to sixty is more than enough for my daily needs" "Sprint time to sixty is increased to 4.8 seconds from 4.4 in the Model 3 and top speed also drops by 10 mph to 135 mph."
I can see how faster is always better, but if 4.4 is "more than enough" as you said, how can 4.8 be too slow? Do you really think that the appropriate place to draw the line between 4.5 and 4.8? If so, can you expound upon how decided that what where to draw the line? Or are you saying that you frequently exceed 135mph? And in either case, why not consider the Performance Y if 4.8/135 is too slow?
4 - The Y is slightly more prone to leaning through the corners.
Have you driven an Y on a hard corner? If you have driven the Y on a track, please share more details. That would be far more interesting than the story you published. And if you have not driven the Y (most likely given the number of Y's out there at this point), how can you say that you don't like they way it handles?
I can think of plenty of other reasons to prefer the 3, but the only valid reason discussed is the subjective appearance. Did you really need to write 2 pages to say that you think the 3 would look better sitting in your driveway?
