I have a 1994 2120. The 2120 is basically a 2100 series frame with a triple component group. The frame has carbon main tubes, aluminium stays and fork. A very smooth ride that compares favorably to mosts bikes in its class today. Not as stiff as current generation OCLV but I am a heavy rider and have had no problems with BB flex. The components are basically 105 level. Mine came with a mixed group and bar-end shifters (STI hadn't made its way to 105 that year) but later models seem to have STI brifters and full 105.
I like mine very much and recently decided to upgrade it to Campy Ergo rather rather than go to a new bike. If I was a racer, I probably would have chosen differently, but in the "sport touring" category the 2120 is still a valid choice.
Looks similar to mine except for the RX100 shifters so it is probably a 95-96. The RX100 stuff is roughly comparable to 105 and was probably used because 105 was not triple compatible at the time. The pictures could be better, but it looks like it has a mountain group rear derailleur (like Deore LX) which is fine - once again it simply dates the bike.
I assume the wheels are the stock Matrix ones Trek put on its mid-level bikes. They were good, but depending on how much the bike has been ridden they could begin to show their age. I recently replaced my set after the rear started to pop spokes right and left. I could have relaced them, but it was time for a change.
Since this is a 60cm bike, if you are both tall AND heavy you might find that the frames flexes too much for your tastes, as the flex is more pronounced in larger frame sizes. I have a 56cm and am perfectly happy but YMMV.
With all carbon bikes you would want to know if the "scratches" are superficial or deep. Deep scratches in the carbon main tubes can lead to eventual failure.
I have seen 2120s go for $250 on eBay. If you get it cheaply enough that could overcome the uncertainty re. the condition of the components and you would get IMO a superior frame. If you needed to replace a few components you would still be ahead of the game in terms of cost and quality vs the Trek 1000 (which comes with Shimano's bottom of the line Sora group - two steps below 105).
Still, you need to factor in the risks re. the condition of the bike and whether it will fit. You should also consider things like free adjustments and other support if your LBS offers them with new bikes. Finally there is the thrill of a shiny new bike if that sort of thing works for you. Personally I like the idea of someone else take the new bike depreciation hit.
One final thought. If you can swing the price of a new Trek 1000, you should be able to pick up a better quality used bike locally where you can see it and ride it before you buy. Triples road bikes are less common than doubles, but there are more of them every year.
Sounds about right. If a 60cm frame usually fits you the 2120 probably will too. Trek's geometry is pretty middle of the road. The stem looks like it may be a bit short, but it is hard to tell from the pictures, but whether is was or not would depend on your torso and reach. If you did need to replace it 1" quill stems are still available, although the selection is somewhat limited.
thanks for the input. So what your saying is I should go to my LBS and see if they have a used bike that is better than the 1000, but comparable in price? How much do you think a used 2004 2300 would go for?

The frame on the earlier Trek CF/AL carbon fiber composite bikes were produced by the same folks who make my Aegis (they were called MountainBik at the time). The 2500/2300/2100 were excellent pre-OCLV frames.
Re. going to a LBS for used bikes - in my area that wouldn't work as very few shops actually have them. Your area may be different, but I was referring more to private party ads.
Re. a 2004 Trek 2300, you are talking about an entirely different price point. New 2004 models are still in the stores at around $2K, so even if you found a used one it will not have depreciated all that much. You usually have to go back at least a couple of model years to get a real deal.
I haven't ridden any of the current model Trek 2100-2300 bikes, but I have ridden a Felt with similar aluminium main triangle/carbon stays configuration. I didn't think it had the smoothness of my 2120, but Trek's version could be quite different.
