These don't come for sale very often and this Is the ORIGINAL. Execuhitch and Invisihitch combined several years back and then went out of business. Their product while pricey is awesome. There is a new company now (only one that I am aware of) in the US selling these under mount hitches but the attachments are not compatible. Their name is Stealth. They make a good product that I have on my X5 F15 but I like this hitch better. I shopped this out on stealth website because I don't have my original receipt and they are over $1200 for the hitch, wiring harness, and three attachments. When I sold my E70 X5 I kept the extra attachments. The 1 1/4" square tube receiver is very popular for carrying bike racks and such. I have two ball hitches with different drops. Other than being hidden when not in use, I love that the hitch doesn't rattle and clank when going down the road since it's a solid design and not the square tube design on ball hitch.
I have the complete installation manual with wiring diagrams. I have the quick connect wire taps, and 2 keys to lock on hitch. I am not shipping this due to weight. I am in Cookeville, TN.
