Factory specs show the 123.133 and 123.153 were rated the same curb weight (3495 lbs, likely without fuel) and the same 0-100kph time (14.0 seconds). That's probably right around 13.5 from 0-60mph, based on other factory specs on models where MB published both metric and English data. The 1985 CA models with trap oxidizer were rated 5hp less, and 0.5 second slower, at least partly due to the taller differential ratio.

I don't have the SD specs offhand, but I believe those were in the 14-15 second range...?

If you have Excel, you can poke around this spreadsheet, see the second tab. I need to convert this to PDF:
