The accessories don't really have much bearing on the price. Check the actual condition of the unit especially the more expensive parts like the tranny and engine.

The price you quoted is reasonable enough for a private party seller. I was at Autocamp, Wheels to Go, Goldpark, etc. today and all their Galants were north of Php200k irregardles of whether Super Saloon or VR. Even GlennSter is asking more than Php190k for his Galant (naka-display sa Kamias).
