ANOTHER Hitch thread!

[Dubs]

Hi all, I have been reading this thread and i am getting myself a little confused.

I rang the stealership here and they want AUD$1982.00 for OEM installed.

I am looking at other options.

1. 00-06 02 03 04 05 BMW X5 Class 3 Trailer Receiver Hitch : eBay Motors (item 230447033718 end time Apr-07-10 18:01:05 PDT)

2 . 05 06 BMW X5 Receiver Trailer Hitch 13070 : eBay Motors (item 170459403209 end time Apr-13-10 18:10:56 PDT)

I see that 1 + 2 mount differently, could someone please tell me which would be more sturdy for the car?

Thanks
