What Car Should I Get?

I have an 02' Chevy S-10 extended LS with only 51,000 Miles on it and some extras.
I'm most likely going to sell it or trade it in.
I really want to get a car that can actually fit people in it, good MPG, and reliable.
I've been looking at (BRAND WISE) Honda's, Toyota's, Mazda's, and Kia's….
Does anyone have any sugestions with experience on what i should get? Thank you.

Car makes noise when I go over 65mph?

Hey guys!

I drive a 2001 Kia Rio. (recently gifted by my uncle so I don't know the complete history of the car) I noticed that when i go above 65 mph on the highway, it makes a strange whooing noise? Kind of like when it's windy outside and you can hear it from inside. I don't know too much about cars but I just wan to be sure that it's not something to be concerned about. Anyone have any thoughts? Thanks!

What size exhaust should i get?

I am getting a duel exhaust on my 1993 gmc sierra with 5.7L 350 engine.What size pipes should i get 2 or 2 1/4 or 2.5 diameter? I know that if you increase diameter you get a deeper exhaust tone? I want a deeper tone but i know if you go too big it can be bad for your engine so which one would you chose for my engine?

Which Sporty Car Should I Get?

Okay so heres the rundown. Ive been looking into getting a new car recently and I am trying to figure out which is the best for me. It is going to be my daily driver, so reliability and gas mileage are big. I live in metro Atlanta so I do mostly city commuting. I want one that defiantly is quick but really fun in the corners too, and I have narrowed it down to these choices -
They're all about 9-10k.

2001 Lexus IS300, 135k miles, aftermarket suspension and exhaust

2002 Subaru WRX Wagon, 105k miles, stock

2004 Volkswagen GTI, 104k miles, aftermarket intake, exhaust, lowering springs and touch screen head unit

2002 Mustang GT, 72k miles, Flowmaster exhaust and cold air intake

Right now I'm leaning towards the mustang because it is the fastest and has so few miles in comparison to the others. Any input is appreciated! Thanks!

What small car should I buy?

I have spent some time now looking into what small car to buy (24yo and my first car), it is proving difficult because there is so much out there and a lot of conflicting information from my friends and family. Wish it was a little simpler! Ok I wanted to buy a new car except because it is my first car, some people think that its a better option to buy a recently second hand car. So I am quite confused! Not sure where to start, really need one for only social reasons as I catch the bus to and from work and enjoy walking most places otherwise. I am interested in perhaps a Volkswagen Polo because it is European also maybe a Smart car. Understand servicing is a huge consideration for me too. Thank you for your help in advance!!!!
