Ugh. I can only imagine what a miserable little car this is. I test-drove a 118d for a couple of days a few months ago fully expecting to love it, but in fact I can honestly say it was one of the most unappealing cars I've ever driven.
It was grossly over-geared, felt horribly lethargic, did about 5 mpg less than my car at the time (a 2.0 Golf GT TDi), and was absurdly cramped (I wasn't expecting much, but the ability to use the rear doors without first removing my feet would have been nice), had unpleasantly offset pedals, nasty small flat seats, and... oh it was just awful!
I'm sure a 130i would put a smile on my face despite all the design shortcomings, however these small diesel 1-series' are without any redeeming features to my knowledge.
My current 2.0 TDi A3 does 58 mpg without difficulty (when it's not in the garage as it is now), and the automatic 3.0 TDi A6 I have as a loan car is doing 40. BMW can poke their not so efficient dynamics as far as I'm concerned!
Ah, I feel better for that...... :o)
