Buying my first Car/Mustang

Hey Guys and Girls,


I'm looking at buying my first car ever. I'm 19 and live in Massachusetts. I'm looking at some Mustangs(huge fan since I was little). I'm having trouble. The mustangs I've been looking at are up to $20,000. Here's the Mustangs


2014 Ford Mustang V6 Premium
$19,373 with 36,976 miles.


2012 Ford Mustang V6 Premium
$17,998 with 18,360 miles


My Problem is that I'm a first time car buyer(I do have Good credit). My dad is telling me to buy a car less then $6,000 but all those cars have over 100,000 miles. I would finance the car and pay monthly also I would have to pay insurance. What do you guys thing buy a car close to $20,000 with lower miles or buy a car less then $6,000 with high miles for a first car. (was looking at mustangs for less then $6,000)


Thank You
