Michael:

Have you ever tried to time 0 - 60 in your 300D 2.5 Turbo?

I just got a 1987 300TDT. Similar engine as yours but with one extra cylinder. I thought it was pretty fast in town or on the highway. I timed 0 - 60 three times in three different days now and the average is 12 seconds. Would love to hear your numbers if you have.
