Ski bag ideas-

[Pica-Pica]

I have never needed an estate/touring. My F30 BMW with fold down rear seats is fine, I can get the occasional long planks of wood in. I use a cheap plastic ‘tarpaulin’ to wrap around. Ideally I would like a cheap version of a ski bag for when I load-through. I’m not paying for a top-price ski bag, and I imagine they may not be wide enough. Any ideas?

(If I ever went estate, do any have a fold down FRONT passenger seat? I believe Honda Civic Touring used to.)
