back from my vacation i will show you the new SLK 280 with 7 GTronic and the old SLK 320 from my mother.
She get's the new one in 3 weeks and i could test it during my vacation,because the Dealership use it as test car, then you will get it cheaper.
It's a big difference especially the sound and the gearbox.
Now the 280 V6 has 231 hp , the old 320 V6 has 218 hp , but with the new gearbox it's more powerful , it accelerates like a rubberband.
