Car Electrical Issue 96 Ford Mustang?

As I was driving home on the highway Sunday my electrical systems slowly died. The gauge indicated a very low battery charge. Once I eventually lost everything I pulled to the side, yanked my battery to charge it at Autozone and put it back in to get the car home before I put a new alternator in. With my now half recharged battery I made it back home. Tuesday I install a new alternator and the car drives around just fine and with a healthy reading on voltage. Unfortunately, this morning, as I turned my ignition the car made little to no effort to turn.

The battery is fairly new (about a year old), with no indication of bad terminals and Autozone acknowledged there were no issues with the battery when charging it. I'm clueless as to what it is at this point. Any ideas?

What vehicle should I buy? Motorcycle or car?

TL;DR? Out of the list below which should I get.

So let me give you some background info. 3 years driving experience. I've driven a 2000 Ford Mustang V6 Auto, 2016 Chevy Equinox Auto V6 (I think), 2015 Nissan Altima Not sure on the engine. I've also driven a 50cc Scooter and rode passenger on a 1300cc cruiser and a 250cc thrasher or motard or something along those lines.
What I like in my vehicle, I like going fast, but not the 120 MPH super speed kinda fast. I like accelerating really quick. I'm very interested in learning how to drift a car or learning how to stunt a bike. So RWD Manuals are a must. Good modding platforms are always a good thing. I like small cars or muscle cars/pony cars. I like sports bikes and cafe racers, pref sports bikes though.

My options
250 Ninja
GSXR 600
Katana 600
Katana 750
Buell Blast
F4i
CBR600
BMW 328i and other driftable models
SN95 Mustangs V6 and GT
1985 Corvette w/ Z 51 Package.
Miatas
MR2 (I think)

Consider these to be in fair to good condition, mechanically sound or very minor fixes or fixes that won't lead to much harm. For ex. The Mustang GT needs a throwout bearing, not a big deal just needs it done.

There are few other cars and bikes I can't remember.

Added (1). Edit: Limit is give or take $3000

Disclaimer: Don't read me the riot act on buying a cheap car please. Not to be rude, but I do have eyes and will look at the vast majority of vehicles before buying.

Added (2). Edit: Forgot to mention it'll be a daily.

New Ford Mustang traction issue?

I recently purchased a 2015 Ford Mustang Ecoboost and have noticed ever since i purchased it (2 months ago) that the rear tires don't have that well of traction while turning. It has Hankook Ventus S1 Noble2 and the tread wear on it is minimal since its a new car. Even when I make a turn(going 15-20 mph, low rpm), it will feel like the whole back of my car slides/drifts into alignment with the car. Almost feels as if the road is slightly wet, even on a sunny day with dry streets. Today it rained and when i was driving I had to be even more cautious. I was driving down a straight shot with no cars around me and wanted to see how well my tires grip in the rain, so i accelerated to 3500/4000 rpm and my back tires started to spin out and the back of the car started shifting hard to the right with each press of the gas. Very scary and felt like there was no tread at all, but the tires are new. I've bought new tires for my old VW(less powerful engine) and it never did that even when I floored it on a wet road, so I know it can't be the horsepower causing it. What can be the issue? Is this common with new tires or can they be defective? The tires look amazing and are very wide and look like they d grip well, but they don't… Any help or advice would be appreciated, thank you!

Added (1). On dry roads, I can floor it without this happening. Its not something that necessarily makes the car dangerous or scary to drive in normal conditions. I still LOVE driving it, just scared one day the rear might whip too much into a curb or another car.It only happens when making turns and driving on wet roads.

Is this normal for my mustang to do this?

Have a 2013 ford mustang v6 with about 38k miles. Automatic. When i'm driving lets say in a parking lot I let off the gas and the engine rpms kinda stay right where they were before I let off. They do get lower very slowly. But when I hit tye brake they lower alot obviously. Is this normal for the rpms to stay arounf where they were before letting off? Also if i'm coasting downhill at very low speeds like 20 mps I will hear the rpms surging up and down by about 200 rpm
Also i'm hearing a rear end clunk when accelerating from a stop or roll. The ford tech said its differential backlash and its normal by why would it be clunking?

2016 Honda Accord Coupe vs 2015 Ford Mustang V6?

Which one would be better for a first car? I'm
Under 25 so insurance may be a problem for the mustang, I plan to keep the car until I graduate college or a year before that. I also care about looks more than speed. Also I want to know which one is cheaper to maintain since I live in the USA.

Does a car lose power after a crash?

There was two lanes to turn left onto a freeway ramp. I was on the right lane as I was turning the truck on my left didn't see me and clipped my front left fender and clipped my front left fender and ripped my bumper off with the back of his truck. After the crash my car hasn't been the same. The engine feels different and makes noises sometimes. The clutch feels more rough now and makes louder noises when I change gears. The car feels weaker over all but none of the service lights or check engine lights are on or anything like that. I have a 2013 Ford Mustang GT by the way.
