i would however advise to avoid the terrible scotch lock things and actually solder your joints as i never trust it otherwise.
I've fitted a detachable witter bar to my Subaru, very sturdy and well designed and i've been very impressed with it.
I'd highly recommend getting 13pin electrics fitted unless your feeling rather quaint and want the old skool 7 pin for reasons known only to yourself.
If your pretty hand with a spanner they're not too bad to fit, again with the electrics i would however advise to avoid the terrible scotch lock things and actually solder your joints as i never trust it otherwise.

We had an older version of that and it was excellent it tipped down so you could open the boot and you could fit 3 adult and 2 kids bikes in between and was solid, no bouncing you hardly knew it was there.
