Hello ! Actually come from the BMW warehouse, so I am an absolute Mercedes newcomer, and need some information about buying a SLK for a friend. This morning we had a SLK 200 K to test together. The test drive was very pleasant, even the “small” engine seems to offer quite enough power, quite powerful. But now we or they have the spoilt of choice between buying a new SLK 200 K and a SLK 280 leader with 4000 km of running power. Price for both e would be identical and is at 44k. (list price for the SLK 200 : 44000, SLK 280 : 54000, both of course FL) Actually the decision seems to be clear (SLK 280), but the SLK 280 lacks the sound system as well as the iPod connection. Therefore my question : is the difference to the serial sound system worthwhile or is the normal system enough ? Supposedly, the USB interface can also be retrofitted, but should then cost about 400 euros. Furthermore, my friend is interested in whether the 20 0er is more recommended with automatic or with gear shift. Look forward to any helpful answer.
