I previously owned a 190D, 1984, and it was very slow. When I first got it, it would not go over 45 but after some filter changing, it sped up to normal. I have also driven a 240D. In my opinion, the 190D seemed to be a little quicker. My guess would be that the 190D weighed slightly less than the 240D. This is just my opinion though, and you know what those are like, earlobes, everyone has two and some have holes in them
