Ive got an eye on a second hand Martinez MCG40C. Some accessories (gigbag, tuner, capo, stand, some books) are included.
Newprice here is 260 US$

I thought around 150 US$ would be a good price, but seller finds that way too low.
What are your 2 cents?
The accessories are worth very little used so I would say your offer is spot on for the guitar.
