Niño don't do it bro! You know your car it's a safe bet, after all that money time and effort it's not worth it... If you had a sudden new amount of dispensable income than do it but don't get a loan or finance, and if you are going to then get one that is completely standard, completely... As your buying on borrowed money and there will be less chance it's been thrashed or played with.
Just my advice brother but be lucky
