www.pok-ter.pl make ones specifically for the 126 in various colours and styles, these ones cost about £50 including postage. Quality seems excellent, and certainly better looking than my previous normal car sized ones.
Also did an oil change. I'm used to doing them but I still wish it wasn't such a hassle... I miss the convenience of normal oil filters!
Behold, some new 15w40 API
SG oil off eBay (a German company called Mannol makes it)
