240D is what 60HP?
The 300td is 112 HP. I bet you notice the difference.
Than I believe the glow plugs and injectors are the same technology, so not likely any improvement on cold start.
Block heater usually do the trick, although living in CA I tried to use it only once in my life on W124, that had the heater factory installed.
Once you start the engine in the morning, reheating it afternoon at work is not that critical.
Than not knowing the budget it is hard to advice anything.
Would you have about 8 grands you can look for 98-99 turbo diesel in W210. Not only way advance body, but the 174 ponies will give you nice kick in the back after much easier start.
My diesel fires up on the first turn even at the slight freezing we have here occasionally or after whole day sitting at ski resort below 20F.
