Bike carrier - which one?

[Beetle_Juice]

Hi all,

 

just would like some advice on new bike carrier.

about to get a new bmw 1 series and the tow bar on these cars is definately not the same as the one on my car now, as with my current one i took off the tow hitch and bolted the carrier to the bar - with the bmw it doesn't have that attachment - its just the hitch - so what type of carrier am i going to be looking for for this car??

 

thanks
