ok well id chose a s2k over a Z anyday, a 350z has about 50 more hp then a s2k but it also weighs 500 pounds more then a s2k, an s2k is Almost as fast as an 350z. s2k have alot less Problems then a 350z has. 350z looks fu**ing ugly in a convertible and uhh Vtech sounds better, but this is my opinion, everyone is different
