So i am looking to buy a used amg sports car and i have found 3 i like all within similar price ranges. I am trying to decide which is the best but i need help because i am no expert on mb cars. The cars i am trying to compare are the 07 amg sl55, 07 amg slk55 and 04 amg sl65. Which is the best choice out of the three? I want a car that i can drive hard and generally have fun with while still being comfortable. It should be able to hold a medium size suitcase just in case i go on a road trip. I also might add some performance parts to it eventually.
Thanks
