2008 Ford Mustang clutch problems?

I have a 2008 Ford mustang v6 stick that is having a problem. Clutch feel is great and has no problems. You can turn the car on and it runs. But when you put it into gear, nothing happens. Even if you leave it in gear and take your foot off the clutch, it stays running. It won't move at all. Does anyone know the cause?

Trading in my Mustang Ecoboost for a GT?

I rececently bought a 2016 Ford Mustang Ecoboost Premium with Performance package it was 36,500. I gave 12k down and am currently financing 24,000. I'm regretting my decision and want to trade it in for a GT Premium. I've only had it for 3 months and it currently has 600 miles. I want to know what to do. Should I trade it in now or should I wait few a months?

Added (1). I'm also 20 so my insurance rates are high. I'm turning 21 in 3 months so my insurance rates should go down a bit. I'm currently paying $400 on the car and $315 on insurance.

What could be the problem with my window?

Ok I have an 03 Ford Mustang. My driver side window was working fine but the passenger window wouldn't go down. Then one day I tried to let the driver side window down it wouldn't move no buz nor did the window look like it was trying to move. What's crazy is the passenger side started working. Can someone help me with this? Just in case if I have to go to the shop about how much would this cost to fix?

2012 Mustang or 1995 Cobra?

I have a V6 2012 mustang with a few after market parts on it. The thing that makes this stand out is its 1 out of 26 lava red V6 coupe mustangs ever made. They are rare/hard to get ahold of and I'm one of the 26 proud owners. (Facts from actual Ford Mustang charts) I have a guy who is ready to trade me his 95 Cobra and below are some of the mods in it:
Built 306 & Pro Charged, 03 Cobra wheels w/ Nitto555's, 90K original miles, full exhaust, cammed, receipts in over 10K, DYNO SHEET SHOWING 530HP at rear wheels, Suspension kit, Aluminum Drive Shaft, MSD, Holley, New centerforced clutch, 12 gallon fuel cell w/ 60# injectors high flow fuel pump and fuel rails.

The Pro is its a fast car that will smoke my 2012 no problem from take offs, and already upgraded.
The Con is its the body I hate, and repairs on parts will get really expensive to fix to keep the speed on the 95 perfect, not to mention it would be one of my daily drivers, but I do love fast daily drivers.

Opinions please?
