1999 Hoss Convertible
Although it doesn't appear to be in the best condition even though you stated 'super clean' (the photos are so-so, especially the engine compartment) I do know that a HOSS convertible with a 6 speed is a very unusual find. I don't know the production numbers but probably less than 100 were ever built. I didn't even know you could get cloth seats with the SS package. I just don't know personally but make sure it's a real SS.
From what I can see in the photos I am concerned about the back window as it looks like it might be having some issues with the top (coming loose). Professional repairs for convertibles can be expensive. You have to make sure the top operates properly when you go to inspect it. Check all the rubber seals around the doors, etc.. because if the rubber wasn't maintained, and has become dried out, you are going to have leaks.
I'm guessing the car was garaged from photo #2 which is important for 'verts. How's the paint up close? Any body damage? I agree with you about that exhaust and I hope the car wasn't run too hard. The history of the car will be very important such as number of owners, maintenance, Carfax, etc... as everything affects the pricing. A beautifully maintained one or two owner HOSS 'vert, even with those 80k miles, would be very desirable and probably get thousands of dollars over any book value. This one, without knowing any details, just book value even with the rarity factor. If the car needs work, $6,000 would be about as high as you should go as it may need thousands to make it right, and that's provided the paint is OK. Having $10k TOTAL into this unusual beast after maintenance, new exhaust, tires, repairs, etc.. would be fine in my book if you plan on keeping it awhile. Of course all this is up to you, but this doesn't appear to be a 'turn-key' show car that commands top dollar. What is he asking? More info will help us out determine a price. We don't even know about the running condition, clutch, tranny, anything. Good luck with everything.
Still a good idea to check for SS authenticity though, especially since it's as simple as looking at the SPID sticker on the driver's door jamb for the "WU8" code (and make sure the VIN on that sticker matches the VIN on the dash).
I definitely agree with NC01TA on the condition assessment; I wouldn't call the car "super clean" based on those pics. It looks a bit dingy and would certainly need a bunch of detailing to be at its best. I have zero experience with the convertible specific issues, so I have nothing to add/offer there. I do agree that the exhaust/rear valance is quite polarizing and, if anything, hurts value. I would eliminate that ASAP if I were buying the car.
Hard to nail down a price on this one. HOSS M6 convertibles absolutely do not grow on trees. This car is anything BUT "garden variety". I would think its market value could range quite a bit depending on who's in the market, how well it's advertised, how quickly the seller wants it gone and, of course, how well it drives/checks out in person. I would think that a car like this could have a range of several thousand dollars in value based on the aforementioned factors. If he is looking for "show car/top tier" type money though, then I would walk away as the presentation and level of apparent cosmetic care does not warrant such. Having said that, if an HOSS M6 'vert is your dream car then you might not get another chance at one, so that would have to be considered when deciding on your personal top dollar offer.
I bought my first HOSS 6-speed hardtop, medium gray leather interior with only 41k miles for $14,500 back in 2014. I added another HOSS auto t-top, cloth interior with 54k miles (damage to front bumper, passenger rocker panel, missing fog lights, and a few other miscellaneous defects) to the collection for $7,500. That's right. $7,500. Steal of the century if you ask me. But I parted ways with it just recently for $11,700 (split profits with my friend...long story short...We bought it to flip and I eventually couldn't resist the urge to keep it...So I did...until I found a unicorn HOSS in January 2018). Great car and worth every penny of $11,700. Sure, it needed some work but for only having 56k miles and in near perfect condition minus the above flaws, it was a great car for a great price and went to a great enthusiast.
Anywho...back to my third HOSS purchase. HOSS 6-speed t-top, white leather interior with only 19k miles for only $16,500 (literally stole it). These cars definitely hold their value. I have seen 3 HOSS Camaros with white leather listed/sell for $20k+. They also sat on the market for a little while. The range in prices definitely fluctuates but every now and then you get lucky. If you have the patience to wait for the right deal to come along, they are still out there. On the flipside, the car is worth what you are willing to pay for it. They aren't making any new 98-02 Camaros so the ones that are out there in great shape are definitely becoming true survivors! Hope this helps. I know I enjoy my current two HOSSs! Good luck!

Excluding the HO color factor, I couldn't see a 19k mile '99 M6 SS selling for more than $14-15k even if the car was as perfect as any 19k mile car could possibly be (about 12 months back we saw an exceptionally nice and highly detailed red 7k mile '98 SS M6 sell for $14.5k). So you paid roughly a ~$2000 premium for the color IMO (which seems reasonable considering the supply/demand for these cars).
