Car Repair

So i just installed new speakers today in my car then i pull out of my driveway to park infront of my dads car and then instead of pressing the brake i press the gas and slam into the back of his car with mine, the back was screwed up and cost 1800 to repair is that a lot to spend on a 2000 mazda protege or not

Call around and get multiple prices and compare them and then you will see what is expensive and where the price should be.
