While I don't think I'm that old yet, one thing I've learned so far in life is to not waste too much energy on the small things. Too many unknowns to get worked up over, especially when estimating the MAX loss you might take due to this issue (I don't think it would be all that high...).
If you like the car, just move on and not waste the energy. When you sit there and question whether or not you should seek compensation... it's a good indicator that it's just better to move on. Wait for that truly big thing that comes along that you will have to deal with.
