About to purchase a 1995 monty carlo z34, 2d coupe, less than 40,000 miles, are there any known issues before i do it? What about price, how much should i spend?

 

The 5th Gen MC's are great cars and will last many miles if you take care of it. 40k is low miles for sure. I would say if you can get it for 5,000 or less you have got a pretty good deal, but just to make sure check the Kelly Blue book site to see what it is worth there.
I would check the fluid dip stick and make sure the oil is clean, also check the Trans fluid to see if its red and not brown. Make sure the seats are not torn if it has a leather interior you can use Baby oil on it to get the Leather conditioned back up

 

Well, with that advice coming from the man, the myth, the legend. the forum member with the sweetest 5th Gen, follow it. And from now on just ask yourself "WWDD" What would Dean Do? Get on down Sarge, clean, Mr. Clean, from some South Nebraska corn field.
