Welcome To Bike Forms, Jay!
That 2005 Trek SLR 1500 could have extensive mileage on it. How would you really know? There's no way to verify what the seller is saying. Since aluminum has stress fatigue issues, one needs to have some concern.
What if the bike actually has thousands of miles on it? ....What if it was used for downhill mountain bike racing for the summer of '07? ...Without knowing its history, you're gambling?
However, you can still make a fair purchase, as long as these things are considered in the final sale, and as long as you make an accurate assessment of the value of the components.
So whatever you think you could get for the used components on the free market plus whatever you're willing to gamble on the frame, sounds about right to me.
Let's see...For a seven year old aluminum frame, I'll wager about a hundred bucks!

^ Any frame of any material can fail. However, the odds that a 7 year old aluminum frame is close to failing from metal fatigue are deminimis. If the frame appears to be in good shape, no dings, no oxidation, and no visible cracks, the likelyhood that the frame is going to fail in the next 20 years are about the same as the odds for a new aluminum frame.

Otherwise, if we go by science and the actual properties contained by the elements and their alloys, we would have to abide by the studies which been conducted by hundreds of scientists for well over the past century.
I have provided links within my signature space for anyone who's interested to study. I will also leave you with what at least one of the industry's manufacturers thinks of the various frame materials, given their varied warranties: https://motobecane.com/warranty/

I have a 2007 trek 1500 which I bought from a guy on CL for $650 about 2 months ago.
He claimed to only have 1800 miles on it, though I had no way of verifying.
I believe I paid about $50 more than the actual value of the bike, but its peak buying season and modern road bikes with aluminum frame/carbon fork, and 105 or greater components were flying off craigslist within hours of being posted.

Note that the Carbon and the Aluminum frames did better than your precious steel frames.
For anecdotal data, Canondale has been building high quality Aluminum frames for about 30 years now. There are still tons of 10-20 year old C'dales going just fine.
I get that Aluminum, unlike Steel and Ti, does not have a fatigue limit, so every cycle is theoretically bringing the frame one step closer to failure.
However, Frame builders working with Aluminum also have understood this for quite some time, and build Aluminum frames with this in mind.

While it's true that aluminum is by nature more prone to stress and fatigue failures than steel, those tendencies can be mitigated by good design. To demonstrate, just look at an airplane. They're typically made of aluminum and are subjected to a whole lot more flex and stress than my bicycle frame. Ever look out the window when you're flying and notice how many feet those wing tips deflect under load and turbulence? But do they become brittle and break off? How many 60-year-old B-52's have fallen out of the sky lately?

look at this site . I think the $'s are on the high side and know one knows what these bikes actually sell for.
I paid $250 for the same bike , but it wasn't pristine by any stretch . Has been very dependable with a little cleaning and tuning and the components work very well . Used bike prices are all over the board. If there are no visable cracks or dents I wouldn't worry about the frame . You usually can tell how a bike has been treated by its overall condition.
