I've never owned either, but had friends with both. The two B2 owners loved them, but didn't care for the 2.9's lack of power. One had a 3 speed auto that sucked pretty bad too. However, I would still choose it over the FSB because of one simple thing. Gas mileage. I know several former owners of FSB's. Each one has complained of the fuel consumption. This goes for the 302 and especially the 351.
Just my observations.
