I just realized something interesting. The article cites a $6000 difference in price compared to the MS3. In the United States, the prices are essentially identical ($22,995 including fees for the SRT4; $22,935 including fees for the MS3). The SRT4 gains 8% of its MSRP in Canada; the MS3 gains 26%.
So when you're frustrated that you don't get Chrysler's lifetime powertrain warranty, remember Chrysler does throw Canada a bone now and then. And that lifetime warranty never applied to SRT models to begin with.
