the old one looks a lot like a "boy racer" car. Age from 18 to 25 may like it. but won't attract people over 30, in my opinion.
on the other hand, the new one appear to wider age group. i think it is a good improvement.
some cars you may like a lot when you are at younger age, but don't like it as much after few years. one reason may because the design appear to only younger people. so that when a person grow up, he/she will have a change of taste.
