Cheap performance upgrade.

This only works if you've got one of those friggin enormous roof racks, you know, the ones like a pile of scaffolding on yer roof. Take the bloody thing off! I'm getting nearly 10mph on the top end, noticeably better acceleration, much less noise and fully expecting more mpg too. And it didn't cost a penny

Oh yeah I forgot, me landy doesn't look like a mobile scrap yard anymore either.
