B150 is slow, but most of the cars in our country are (or their drivers are) so it's perfectly adequate for our crowded roads.
The 2009 facelifted B with cd-changer/Audio50/Comand is fitted with the 'Media Interface'. Although I've not seen a car with one fitted, from what I can ascertain from the brochure/web/dealership, it's a box of tricks that replaces the CD storage tray in the glovebox and has a socket into which you can connect a triple-headed cable that allows you to connect an iPod, a USB memory drive or any audio device with a 3.5mm jack. According to the price list, the UK price for the media interface cables is £45 - I read on the web that in Germany it's EUR39! Which works out around £30? ISTR that the USD price is equivalent.
In the UK, for the facelift model the B is available as an 'SE' or a 'Sport'. The SE comes with the fixed glass roof and cheap 16" wheels, the Sport comes with 17" alloys (10 spokes), lowered sports suspension, half-Artico upholstery, and chrome accents on the front fog lamps. Decided I'd rather have the glass roof.
