Roof racks certainly don't make sense functionally, certainly don't hold enough weight to justify, cost extra, and make the care look less sleek. A failed attempt to balance the car, top and bottom with chrome look. Everyone please kindly remove them. Ugg
Unless you're liking the egg/minivan look.. I think roof racks are a necessity, but then most suv drivers are not going off road or doing anything heavy. I have transported a 60" flatpanel, a medium sized shed, and countless trips to IKEA and roof rack is a saver.
I don't know what it's rated for but I would say I've loaded 150 lbs across the cRoss bars
'10 MDX blk/blk
'04 LS430 CL blk/blk (I'm on cloud 9)
'99 RX green/beige - (still smashing, but it's the beater)
When I bought my rx300 it came with the roof rack installed. I never used it till my friend got me helping him fix his house. He has a gulf rabbit. He needed to buy a 40 foot ladder, and guess who he called. Lol
