At the end of the day I think we should be celebrating that in a time of eco-everything and credit crunch and general crappy times for many businesses, that car manufacturers are still producing cars like the Cayman S, the 370Z, the Challenger and the Mustang.
Size, weight, culture, driving dynamics etc will always polarise opinions, I love sharp handling cars, but still love the nostalgia and retro awe surrounding the Challenger. Yes it's no Lotus, and that's why I love it, over the however many years I will be driving in my lifetime I should experience as many petrol/gearhead cars as possible, all have their strengths and weaknesses. It's a big heavy piece of Americana, one that I am not familiar with but look forward to experiencing, same with the Mustang.
Now my family situation (and the weather ha ha) may not lend itself to a 370Z at the moment but that doesn't stop me from wanting one of those as well. In time I hope to own many more small nimble handling cars, maybe a couple of superfast Japanese cars, and definitely a muscle car or two, regardless of cornering prowess.
Rather than slagging these cars and manufacturers off continuously, companies like Nissan should be commended for pushing out edgy designs that go quick and are good value for money, someday these cars might not exist.
Personally I don't think many people would cross shop the 370Z and the Cayman S in the real world, stats don't tell a true story when it comes to marques, people on here should at least know that as we've been down this road many times before.
