I had an after-market head unit installed from the dealer when I baught my 09 Malibu LTZ, they have me the original stock head unit. I was wondering if their was a market for them? And if so how much do they go for? I have two of them since my sister got a malibu as well and had the head unit replaced. Also if someone is interested in buying one or both, they are brand new were never used off lot, they have been sitting in my trunk since we got the cars in November, please make an offer. Thank you
