What's my problem?

I wouldn't worry about the color of the engine compartment, nothing else is stock either. It looks like a nice car, but you said it yourself- pro street cars are hard to sell.

$16k is a lot of money for an A-body that's been heavily modified for drag racing. Mopar folks usually want bone stock. The big money mopars are stock, "rare", and usually not A-bodies. Really nice A-bodies are sold for less than $16k all the time.

I'm sure you probably have 16K or more into the car, so, if you want to keep your price point the same you need to show WHY it's a $16k pro-street car. Get a photobucket account so you can host larger pictures. Take a lot of high quality, BIG pictures showing the detail work. Take some "glamour shots". Make sure everything is in focus, make sure all of the pictures are right side up. A dozen tiny pictures don't show what the car really looks like. It's the little things. All of the pictures in your ad either have shadows, are cropped so you can't see the entire car, are at weird angles, or are upside down. And they're only 500x281. That's tiny.

When I hear "pro-street Duster with tubs, no rear seat, 9" Ford rear and a 4-link" I think hacked up race car. And none of your pictures really prove otherwise. Show all of that work and prove it isn't just a hacked up race car and you'll have more prospective buyers.

For example:

Would you buy this car?



Or this one?



Hint: it's the SAME car. The side moulding was removed and the rims changed, but that's not the biggest visual difference. It's the same car, just a better picture.

I took this one with my iphone in a parking lot. Nothing special, but its a far better picture than any of the ones you posted in your sale ad. If you do a better job of representing your car, I think you'll have a lot more interest. If you want to sell a car for $16k, the pictures should look better than what someone can do with their phone. Drive your car to a park, put it up on a lift at the muffler shop, borrow a camera, etc.
