“Mercedes-Benz E-Class Diesel will get you 45 highway with a lot more car around you.”
Not quite. It's rated for 24 mpg city, 34 highway. It'll probably exceed 34 mpg on the highway on long drives, but I don't think it'll get 45 mpg.
I have a 2005 E-Class CDI diesel, rated for about 33 mpg or 34 mpg on the highway. On a long trip with no interruptions, slow-downs, etc., I get as much as 38 mpg.
Mixed highway/city/sidestreet driving, I get around 30 mpg.
But it is a darned sight nicer to drive, I think, than a Tata.

It's a great idea!
