Is this a good purchase
06 Chrysler 300 167k miles 1900$
I have no way of knowing but the odds are against you.
A used Chrysler and good do not go in the same sentence. $1900 is not a lot for a vehicle, so plan on having some extra laying around for repairs.
Can you afford to lose all your money the next day? Odds are when it breaks down the repairs costs will be several times what you paid for it.
