Obviously you have to explore you opinions. So, you should go to a few dealers around town, you can also look up the trade-in value of the vehicle at www.kbb.com
Insult? $1900 is only $450 below what you paid for it, without the $1500 worth of repairs. I would take that $1900 and buy something else.
Actually I would have taken that $1900 AND the $1500 and bought even a better car. You made the mistake of spending 64% of the total purchase price in repair cost!
