I've just bought a 2005 Yaris 1.4D T3 and am really pleased with it. I was a bit surprised to find that the advertised "trip computer" only displays average mileage on this car. I did try and have a play around with it whilst having a test drive but there were other things I needed to look at too, so the trip computer didn't get that much attention at the time. Is this normal for this model of Yaris or is my trip computer a duff one?!! :(
