I kept a 92 Galant for 2 years and Galant is an excellent car.
@Iffe...Your perception is very wrong. Mitsubishis dont require extra maintenance. They just need routine maintenance like any other car.
A good 94-95 Galant will cost around 500-525K with CNG.
I would say that you go for it.
The older model 1991-92 would cost you around 300-350K.
