So, is this car at a dealership or other commercial-lot car reseller? Or is this a private sale? It sounds like you are unable for some reason to "interview" the owner, and just find some of these things out for some reason, directly? What is this car's history? Single owner? I guess I just don't understand why these things are to you (or would be accepted as) otherwise, a "mystery".
How was this car used? Is it modded heavilly? Used as a track beast? Way too many unanswered questions!! ...And that we, behind our keyboards on the internet - hello - just plain can NOT (possibly) answer for you!
If you can't get FACTUAL - rather than via uninvolved, disconnected 3rd-party "blind" internet users merely GUESSES as to what might be "up" with this car... well then.....
You are a lot closer to this than us! Why can't you just find out more directly, more precisely what this car's history and maintenance records (does it have maintenace records? - What dealership did it originally sell from, do you know?) are? Something is not right / smells a little fishy here.
That price is pretty deep discounted for sure! I would presume that would also be "for a reason". You need to find out what that reason is!
