I DIY'd mine.
Old discarded bed frame angle, some 2 x 2 tubing that I had nd a few rods.
Drilled lots of holes for bungee tie downs.
Used it this week to load/haul fuel for this winter snow blower usage.
I was able to load 4 ea 5 gal plastic jugs and good to go.
Big advantage is no odors in my car.
Total 'out of pocket' was a few rods and electricity.
Very handy.
Oh and on my KIA the car lights are all higher than the rack.
However 'just in case' I attached reflective tape to the back edge of my DIY rack.
