The problem with many new car designs is that most of the car makers follow a trend of what is percieved to be sellable to the masses / market acceptance / style and cost efficient
Since the late 80's many car makers have copied each other in one way shape or form with many using the same basic platform design and even parts sharing to a degree, of course a lot of car makers are owned by the same parent company so its logical to do so, especially when you consider its costs zillions to design and fab new models
Sure the 370 has some improvements as do all " new models ", with some extra fruit, a few extra pony's, new lights, some gadgets etc which usually amounts to an extra arm and a leg and $$$$$$$$$$$$ for the joy of owning one
The problem I have is that they look very similar in style and shape to some Porsche's, and Audi's and are easily mistaken for one of these at a first look until you read the badge unlike the earlier designs which were very individual and styled cars
But thats progress, my thoughts, if you look at the Chrysler crossfire design, this is what I think a modern Z should look like, or you can have one that loses its roof
