I don't know what to say other than, it's a no-brainer. Coyotes are ridiculously nice cars. The power is incredible, linear, and smooth right out of the box. They make 400+ rwhp with a couple of bolt-ons. They're about a million times nicer than SN95s and foxes.
The MT-82 manual transmission can be problematic if you get a bad one. The mainshaft endplay was out of spec on mine, causing lots of noise. The dealer replaced my entire transmission under warranty, but it took seven weeks, and it wasn't a pleasant experience. I've also had problems with the rear brakes on my car, but nothing that wasn't difficult to repair. Now, it appears I have a very small leak in my A/C, but it only took 10 minutes and a can of refrigerant to fix.
The track pack and Brembos aren't a big deal. I wouldn't let that hold you back if you find a car that you otherwise like. Brembos are pretty readily available so they can be added later, and you can either have 4-piston 14" or 6-piston 15" setup from a Shelby. The Brembo cars also come with different shocks/struts/springs, but I hated mine and they shook the tires so hard I thought I was going to snap an axle. After I swapped the shocks/struts/springs on my car for a set of Koni Str.Ts and Steeda Ultralites, the wheel hop was completely gone and the car still rides great. The 13.75" rear brakes can be had off of a GT500 and all you have to do is swap brackets and rotors. It's easy and cheap. Also, don't be too concerned if your car has 3.31 gears. Mine has the track pack with the 3.73s, and they're very steep. The MT-82 has very steep gears compared to what we're used to with the SN95s and foxes. I just switched to a 315/35r20 NT05R, which is about 28.5" tall. That made first gear a little more bearable for me. The fastest guys have the automatic and 3.31s.
Take a look through my Coyote build thread for some ideas on good/easy mods.
