Is 2004 Hyundai Sonata V6 too much for first time teenage driver?

I recently bought 2004 Hyundai Sonata for $3000 (with my money that I earned by working at little caesars)
It is my first car and is my first year driving (yes, I did all driver's training and such).
All my friends have small cars like Toyota Corolla, VW Jetta, and Honda Civics.
I'm aware that my car eats much more cars than my friends cars.
Is my car way too much for me to handle?
Should I sell my car and get a different one?

What car would be better for daily driving?

So my choices are a 2013 Ford focus st, Mitsubishi evo 8 (i don't care about how much it kills your back or how old it is), e90 328i, e90 335i, 2008+ mercedes c class, 2011+ ford mustang gt (because of the 5.0 coyote), mazda rx8 2005+ (obvious reasons their), honda civic si 2012+, 2010+ subaru wrx (not a sti). Let me know what you think, and any other cars that could be worthy are appreciated.
P.S. It has to be a manual

My new car is making noises? Update?

I purchased a new Honda Civic 2015 about two weeks ago. Recently I have been hearing a grinding noise when I slowly press the brakes. Also, when I first start up and switch from park to reverse I hear a grinding noise. I'm certain that it is the car changing gears. However, I haven't heard this in any of my other previous cars (Chevy Cobalt 09) . After all of this I took it to the dealership and he said it was normal. The break noise is caused by the "breaking in" period, and the gear shift is apparently normal and will never stop because the car is cold. He said that the brakes need to mold to something or the other. Is this information true or should I go and hassle them some more? I paid big bucks for this car and expected it not make disgusting grinding noises, please don't kill me for being picky! Haha.

Update… Car is at about 450 miles and the brakes are still making noises, and the transmission is still making a grinding sound when I switch from park to reverse (occasionally.).

Any suggestions? Would I be eligible to return this hunk of junk for another new car?

Should I refinance my car or trade it in?

Okay so this is my current situation, I bought a car for my first time and I'm currently financing it with a bank ($350/month). I owe $12,500 right now but the interest is KIILLING me and I know my credit is really good right now because I'm being approved for ALOT of money. The other thing is that this car has too many miles, it's a 2012 Honda civic with 83,000 miles (Yes I know they messed me over bad but everyone makes rookie mistake). Should I trade it in for a new car or should I refinance this car and risk living with it? Even though I hear Honda are really reliable cars. What should I do?

How to install line output converter (LOC)?

I'm trying to install subs and an amp to my Honda Civic 2012, and I want to keep the factory hu. I've removed the head unit, and behind the head unit there were lots of wires taped together and were plugged into harnesses. There were three harnesses and each one had multiple color wires. I know you have to hook up the R+ wire on the LOC to the R+ wire on the head unit but I don't know which one it is… Plus I don't know how to do that. Do I just cut the wire and connect it to the LOC wire? If I do that then what happens to the harness, do I just plug it back into the stock HU with some of the wires missing/cut out from it? Also where do I put the LOC, the wires are really short so it has to be around the front somewhere. I'm very confused, and am new at this

Does driving on extremely rough roads damage your car?

I was driving to my friends house for the first time a couple days ago and I got lost. I ended up having to drive up this road that was all dirt, extremely cracked and had bunch of crevasses. My car was lurching pretty hard as I was driving up. Does driving on a road such as this cause any problems for your car? My car is a Honda civic 2014 and I was going as slow as possible up hill.
