I test drove a 240D and was shocked by the lack of power. A 300D with 5 cylinder turbo was much better. I hear that the 2.5 turbo is quite good and that the 2.2 in the 190D is very low power. Likely better than the 240D due to the lighter weight. I would like to get a 190D with 2.5 turbo. I am looking for one to test drive.
