A250 Amg Sport or Engineered by Amg?

[JonSpiderMan]

Been looking at this for a company car.

I do quite a few motorway miles so need something that's fairly good on them but also like a good b road blat now and again, question is which one is better, and does the uprated suspension on the engineered one mean It will be a bit too firm for normal motorway stuff or would i be better off with the adaptive suspension on the Amg sport version. Apart from the suspension is there any other performance tweaks to the engineered version.

Also has anyone heard what the Standard Stereo is like, debating whether the Harmon Kardon is worth the 1k outlay and trying to keep the options down, with my first attempt I ended up with about 4k's worth!

Thanks in advance
