I really like the concept, but I have a couple of suggestions:

I think you could reduce the scale of it a bit. Maybe remove the front and rear curved parts? Also, possibly a smaller diameter of tube steel. And only 4, not 6 attachments. I really like the quality of the attachments, but even those could be smaller with only one bolt apiece. Far better than the suction cup and strap ones.

If it were a bit more diminutive and used a little less material you might be able to bring the cost down, and I don't think you'd sacrifice much of the robustness. You can only really put so much weight on the roof of a mini anyway. I have no interest in the light mounts, but I frequently find myself wishing I had a roof rack (especially when my wife takes my truck. 

Sounds like you already have 16 potential buyers...gotta love Facebook!

Close up of attachment- we would suggest adding a little piece of rubber (inner tube?) to isolate the metal from the gutter.

I rather like it.

Interesting- just posted this picture on our Facebook and have 16 people like it!

"Beauty is in the eyes of the beholder"  (Note- this picture was taken on my Riley that I have also been told is Ugly?)

This saying first appeared in the 3rd century BC in Greek. It didn't appear in its current form in print until the 19th century, but in the meantime there were various written forms that expressed much the same thought. In 1588, the English dramatist John Lyly, in his Euphues and his England, wrote:

"...as neere is Fancie to Beautie, as the pricke to the Rose, as the stalke to the rynde, as the earth to the roote."

Shakespeare expressed a similar sentiment in Love's Labours Lost, 1588:

Good Lord Boyet, my beauty, though but mean,
Needs not the painted flourish of your praise:
Beauty is bought by judgement of the eye,
Not utter'd by base sale of chapmen's tongues

Benjamin Franklin, in Poor Richard's Almanack, 1741, wrote:

Beauty, like supreme dominion
Is but supported by opinion

David Hume's Essays, Moral and Political, 1742, include:

"Beauty in things exists merely in the mind which contemplates them."

The person who is widely credited with coining the saying in its current form is Margaret Wolfe Hungerford (née Hamilton), who wrote many books, often under the pseudonym of 'The Duchess'. In Molly Bawn, 1878, there's the line "Beauty is in the eye of the beholder", which is the earliest citation of it that I can find in print.

Sorry Don, but that is just plain UGLY!

How may people would be interested in thei very heavy duty (although is only weights 35lbs.) Cost will not be cheap, probably $699 in steel and $799 in alloy (15lbs in weight). PS- Lights not included.
