I had a dilemma between which car ill choose; the first one or the third one. I finally chose the third one because I think the disavantages arent so bad and the advantages are much better than the other designs. Also, If I was the one who will buy it, ill chose the third one because it has the best design because it is attractive but not ostentatious.
