It's as good as my 20 years younger car - as far as fuel consumption goes anyway.
The best TDi's from a FE point are the mid to late 1990's 1.9L engines with 90 hp - at best mated to a light car.

I am thinking about aerodynamics and don't believe the scenario of that the front is good enough and the name of the game is entirely at the back.

Have you seen the diagram with the streamlined brick ?
You gain by far the most by streamlining the rear end, even if the front is still brick-shaped.
You can gain a little bit by streamlining the front.
Streamlining both ends gives the highest gains - but it's not that much better than with only the rear.
So, modding the front is going to be less time/energy/cost effective than modding the rear.
But obviously, it'll still help.
