Sorry Dave ... to say so.
Please forgive me my opinion here but I don't like it; this is not my personal style.
As it might be a nice contemporary and clearly after-market derived add-on for your (our) car(s) it appears to me to be fitted by screws to the trunk lid.
Or, with other words, you now have holes in your trunk lid that should not be there - as from the factory.
For me (and possibly others here) this is a noticeable deduction of your car's value. :'(
For a real aficionado aluminum welding and repainting with all the color code shading problems is going to be the consequence from this.
If I hunt for a luggage rack then only the one-and-only hardtop-mounted luggage rack
which is unfortunately extremely rare but also extremely beautiful.
