Well sorry to burst your balloon, but I've had many Porsches and other sports cars over the years, and they cost a WHOLE lot more than the xfire. They had 6 plugs, got the same MPG and had a spare. I didn't buy this car as a economy type car, I bought it because of its looks, nothing more. At 50k, the srt is way overpriced, if anyone is stupid enought to pay that. The public has shown how much they admire and demand this car, because the prices are dropping like the Dow Jones in 1929. I doubt that anyone who buys a Chrysler, would even ask how many plugs it had, because they always had 4-6-or 8 in all their cars. But, I'm sorry, its a Mercedes Benz. Its hard to give these cars away at any price. But, like I said, I still like it. When the x-fire has the reputation of a Porsche, get with me and we'll talk about sports cars.
