Bought a ported m90 with a 3.4 of a strange gtp. 2000 model with no hud, had cloth seats, no seat warmers, pretty sure it didnt have a dic, among a few other oddities. Checked the vin, had a 1 for the engine. Checked rpo tag, had l67 on it. Also had a regular gtp harness on the engine. Any opinions?
