Need help Volvo price

I know very very little about where Volvo is at price wise. I have a buddy who is looking at buying a Volvo. It is a 2013 Volvo I do not know the Volvo model numbers, but it has the D13 motor 13 spd with 3:36 rears. It's a road truck well maintained with 1/2 million miles on it. I turn to you guys because I haven't priced a Volvo out in 27 yrs. where should the price be at for a truck like this. I need a ballpark figure. A Pete or kenworth in this condition with these miles would be in the 70-80,000$ range. The guy selling it said to make an offer. It's important that the offer not too low and turn the guy off, but it can't be too high for obvious reasons. I understand that these trucks are everywhere and are a dime a dozen, which makes me think the price should be in the 60 range, does that make sense or am I way off?

Also what should he be looking at? Where are the trouble spots on these trucks?
Thanks,

 

I went there, that's where I'm getting those figures. I asked on here because you guys have bought, sold and driven these models. Figured it would be best to ask someone that's not a salesman. I was actually hoping to hear from you, I thought you were a Volvo guy.

 

It's like I'm speaking a different language. Thanks for your input. It's not that important to me. I told a friend I would poke around with some Volvo guys and get some feedback. So I'll relay your answers of go to the dealership and ask them and visit truck paper to come up with a price.

Gotta hand it to you fellas you know your volvos.

 

He is in your area. Johnson city Tn. The truck is in Bristol Va. I dunno man, personally I told him to leave it alone. But he wants a truck to put a driver in and thinks this one could be decent. I was surprised to see that new ones are in the 140,000$ range. Let's be honest it's a Volvo. I thought this would be a good place to get some info. My fault lol

Thanks Rollin coal, but it's really no big deal man.
