2005 Ford Mustang for my first car?

It is a 6 cylinder, Automatic, 17 mpg (not bad but could be better) I'm 16 and my dad found a great deal on one. Never has had any breakdowns, engine problems etc. The only thing we'll have to do is replace the tires due to the treading being worn. As far as that goes, it's good. QUESTION: I was wondering if that would be good for my first car? Is driving something that low to the ground easy or hard? What's the overall quality and satisfaction you've had with your mustang? (If you've owned one).

Get driving lessons, advanced driving lessons, performance driving lessons. A must. You do not know enough as to driving. Bring dad. He needs lessons as well. Google "teen driving lessons" for courses around your area. I recommend the type with hands on wheels not just the classroom type. Mustangs are basically a Ford cheap car with an engine. This is true since 1964 1/2 when they first came out. It is just a car. Nothing special. But if you get this car, you need training. Start by read the car manual, cover to cover, and learn what information is this booklet. Essential. Many "Warnings" as to safety that are needed to be known. Apparently, dad is living his youth via you. Teens crash over one million times per year, over 400,000 get injured from minor level injuries to handicap for life level ones. Over 5,000 teens die as drivers, passengers or pedestrians due to car crashes. GET ADVANCED DRIVING LESSONS. This person failed to do just that. He is no longer alive. Lessons learned. AND NO CELL PHONE, NO TEXTING, NOT ANYTHING BUT DRIVING 100%.

Financially speaking NO, mustangs are horrible first cars cause being a teenager w/ ZERO driving experience you (or your parents) will be forced to pay a fortune in insurance premiums

They are good cars, but unless your parents are going to pay the insurance for you, then no it's not a good first car. The insurance will be every bit of 400 dollars a month for you. Mustangs are expensive insurance for someone your age.
