FYI: Home Depot sells ratchet straps and rags for less than $10. First time I made this mistake with my car I just padded the roof with rags and ratchet strapped the shit to the roof.
The next time I went I had crossbars and used the same ratchet straps.
I’ve hauled more shit in my $16k sedan on $200 crossbars than 90% of $90k+ superduty pickup owners
