The early W140 300SE was fitted with the 24 valve 3 litre motor from the W124 300E-24 and the R129 300SL-24. It was a good and powerful engine, packing between 221 and 231bhp. I don't know what the torque figure was.

A 300SE will obviously be slower than a 400SE (as they then were) or a 500SE. But it is not a slow car. It will pull 0-60mph in a little under 9 seconds and will go on to 140mph. To extract good performance out of it will obviously require the driver to rev it more than a large capacity V-8.

There is no way this car would "struggle", though!
