  We examine the simplest inflection point quintessence model, with a potential
given by $V(\phi) = V_0 + V_3 \phi^3$. This model can produce either asymptotic
de Sitter expansion or transient acceleration, and we show that it does not
correspond to either pure freezing or thawing behavior. We derive observational
constraints on the initial value of the scalar field, $\phi_i$, and $V_3/V_0$
and find that small values of either $\phi_i$ or $V_3/V_0$ are favored. While
most of the observationally-allowed parameter space yields asymptotic de Sitter
evolution, there is a small region, corresponding to large $V_3/V_0$ and small
$\phi_i$, for which the current accelerated expansion is transient. The latter
behavior is potentially consistent with a cyclic universe.
