Lots of rim braked road bikes going for not much money, as people want discs !

Yup; I was just thinking about this earlier.

As much as I detest a lot of "new tech for the sake of it" and often champion older stuff, there seems to be a real gulf emerging between old and new road bikes; with through-axles and disc brakes bringing a real step change in this regard.

Appears that the used market is flooded with decidedly old looking road bikes from the past 10-15yrs - for the reasons above as well as some really dated looking frames and graphics.

MTBs and low-end utility stuff also seem to be taking a right shoeing, while gravel and more enthusiast-focussed niches seem to be holding their money..

What type of bike are you looking for?
road, MTB, shopping?

Would be worth taking a luggage weighing meter and check to make sure it's not excessively heavy.
E.g. A good road bike should be 10kg or less.
 
I just bought a basic Trek Navigator T30 specifically to mount a Hamax child seat.
I forgot to check if the seat tube was tubular or conical.
I only went and bought the only production bike with a swaged seat tube having a 3" conical section, just where the mount needs to clamp.

Ho hum.

Check if the frame number is there as stolen bikes get them ground off. Under bottom bracket. If the person hurries you or distracts you a lot it is a worth thinking if there is a reason for them doing so. It may just be they are friendly rather than making sure you don't look at something.

Whoopie! My 1986 Dawes Renown would qualify! :-)

I would not buy a used CF bike, any frame damage a lot of the times does not show up on the outside, and unless it is X-Rayed you won't find it, then if you're riding the frame or fork breaks, you're SOL and may end up DOA!!

I have a friend who bought a brand new CF bike, and about 6 months of riding later something blew apart the bike, they don't know if it was the frame, the fork, or one of the wheels, but the whole bike just grenade into bits and pieces. He was in a coma for 3 months, and was told he can never ride a bike again. He can walk and talk and is working after a year of recovery, but he can't do what he loved to do, but his life is more important. Can't provide the name of the brand of bike and wheels due to ongoing lawsuit.

Sorry to hear this - it's such stories (and a reasonable understanding of how composites fail) that keep me well away from such materials in safety-critical applications..
