I bought a Colt 1.5 D (not a Ralliart, but same car), and have to change transmission oil this weekend. I've seen people remove the front left wheel for easier access to the filler plug. Thanks for the video.
I'll have a look. Surprisingly there isn't many being wrecked in Australia and the parts suppliers/wreckers over here are a rip off when it comes to used parts. You can try rhdjapan and go to bid jdm and see if you can get one there.
