If they've been off the track a few years then sure, go take a look, see if they're something you're comfortable with, they certainly might be.
Bear in mind that unless they have had Significant Good Training since their racing days, it can be easy to misunderstand their level of comprehension of normal riding horse things... some ex-racers have little clue about standing still to be mounted yet are fully solid about most other things; many or most of them will take "a constant pull on the reins" as a cue to go FASTER, especially once you are cantering; many have no clue about leg aids; etc. So you need to think of them, even more than you would any other horse that's new to you, as a patchwork of different levels of training, not something all-of-a-piece.
Also it is worth trying to find out how they spook -- either by trying to provoke a mild spook if the seller permits, or at least by ASKING the seller what they do when spooked. With OTT TBs especially (moreso than many other horses), novices should really try to avoid the type whose reaction to something scary is to leave at 40 mph and not stop til your legs fall off. By no means do all TBs react this way but there is a certain subset who that IS their natural pattern of response to anything that worries them, and it is NOT a confidence-building horse for someone who has not got years and years of experience, preferably including some bolters, under their belt. What you want is more along the lines of a horse that spooks in place, or at worst backs off a few strides and then stops and faces the scary thing.
Good luck, have fun,
Pat
