I have a 2007 Mercedes GL500 that has done more than 200,000km and I'm deciding on its replacement. We no longer need seven seats but would like to stay with a large SUV. The AMG ML63-GLE 63 would be an option. What about the Jeep Grand Cherokee SRT8 as an alternative? It looks as if it has all the bells and whistles that the ML63 has, at about half the price. I know the fuel economy is not great, at about 19-20L/100km in the city, but it sounds great and looks mighty quick.
