Hey, I was trying to stay out of it. When I was big into the xterras, I was buying everything for them. I have the roof net, the interior bike rack and tons of other stuff I haven't used in years. Seat covers were well worth it because many times I had stuff spilled that would stain the seat cover and i could throw it in the wash, unlike the actual seat.
When I got too broke to buy all the fun toys, I ended up just using bungie cords for everything, because they work.
