SubiSIR25i

Hey guys, I have someone offering me a 1989 mazda 626 5-speed for $500. I am looking for a manual trans beater to take some slack off my subi. Only cons to the mazda is that there is a HUGE dent on the drivers side by the gas tank door, it needs a pasenger side tail light, and has a hole in the exhaust. Kinda seems stupid to ask but is it worth actually spending $500 on this and putting it on my insurance? Idk if this thing will even pass an inspection haha
