I may have posted this earlier in the thread, but in case I didn't, here's an Excel spreadsheet that has a good number of the factory acceleraion specs:

Note that some factory specs are 0-55mph, some are 0-60mph, and some are 0-100kph (0-62.4 mph). In the mid-80's, when the USA still had that silly 55mph speed limit, the brochures had the 55mph specs. Later on they reverted back to 60mph. Across the pond they use 100kph, and this is also the spec used in the TDM (Tech Data Manual).
