Yes, Trek used bonded aluminum frame technology for a while (glued). They work fine. That era has passed, so alloy frames are now made differently.
Check the vintage Trek site out for details. There was an article there from the late 1980s/early 1990s about Trek's aluminum frame building.

And here is a listing of models/colors by year. While not perfect, this list is VERY useful.

Perfect message by the way. Well done.

Please don't confuse ebay "asking" prices with "selling" prices. Many sellers never get their ask price. some are far from it. Value is determined once an item actually SELLS. Its easy enough to check SOLD prices.
