I've been a proud owner of a Porsche Panamera 4 for several years, but recently decided to trade it in for the new 2017 Porsche Cayman S. Let me tell you, this car is absolutely amazing! From the moment I got behind the wheel, I couldn't stop smiling. The Cayman S is incredibly responsive, lightning fast, and an absolute joy to drive. I spent months researching this car and the reviews were all excellent, but I have to say, it exceeded all my expectations. I love everything about it, from the ride and handling to the comfort and true Porsche driving experience. I thought I would miss my Panamera 4, but the Cayman S has completely won me over. It's truly a remarkable vehicle that I would highly recommend to anyone looking for a thrilling driving experience.
