It is grammatically ambiguous, to be sure. The first part sure sounds like they were - past tense - at breakeven, before they set out on this "Game of Pennies". But then it's not clear whether he's talking about a still-ongoing process to reach what would be a 14,2% margin, or whether he's "storytelling" and has put himself as the narrator into the mindset they were going through (e.g.: "So, I went into the woods to slay the dragon. And that means first I have to find the sword, and then I need to track down the dragon...")
I think what's going on is that the latter part is an ongoing process. That they're currently somewhere between where they were - where "each one basically cost about $3,50 or thereabouts" - and where they need to be - "more like $3,00 on average". And that the route they've taken - including closing stores and the like - will achieve the stated goal in late Q1 or in Q2 - they think. But until all the numbers are crunched in the end, it's impossible to say that they were correct in their calculations.
This is how I interpret it, at least.
A 14,2% margin on the base version would, BTW, easily support an average automotive margin of 25%. Easily.
