the price for a specv is only a few hundred more than the non spec v (read:automatic only) se-r...LSD is optional on the Spec V i believe in one of their packages..
the spec v has 10 more hp (175 vs 165) and has enhanced stability and cornering, over all it really breaks down to whether you can drive stick or not, both cars will kick ass but the spec v will school the automatic version, 4 cylinders + automatic=slow....
