Update
Figured I'd post an update for those of you who are trying to answer the same tough question I am.
Did some google research on local Ford dealers (in my quest to determine the Genesis vs Mustang winner), and after some searching, I found one with a V6 manual and the 3.31 gears. Off we go to the dealership!
Spent a few minutes browsing (they had probably 20 used mustangs of various vintage/configurations) and then I got approached by a salesman who steered me towards the 2011 V6 I had been looking for. It was a red brick color (the darker red) and it was about as base as base gets, with only the spoiler and gears being the added equipment. The salesman was an older gentleman (early/mid 60s), but he knew his product fairly well. After some basic chit chat we got to the drive. We had to get gas first (he though this was the one they had been test driving, but it was a different car). This one was as new as they came, with a whole 29 miles on the OD. While he was filling it up (I sat in passenger seat while he did the driving to the gas station, and I examined the interior.)
Interior thoughts: I liked this interior more than the 2005-2009 models, but it was very.....meh. A lot of hard plastics, not too lively to be quite honest. Now I realize this is the BASE model, but I was hoping for more (the interior on all of the Genesis models blew this one away). We switched spots to start the test drive, and I knew the guy was a little bit nervous (he reminded me of my drivers ed instructor from high school, not condescending, but more afraid for his life

). I had been driving an auto for a while (both previous cars I owned were manuals, so I knew how to drive it) and managed to kill it at the first stop light . After that it was smooth sailing. The interior sitting in the driver seat didn't seem as bad (the chrome accents and light blue guage color helped), but again, not on par with the Genesis. Then we got to some driving.
Motor and transmission: Now THIS is what I'm talking about! I was impressed, a lot. I honestly thought this was going to be Civic esque power delivery (peaky horsepower numbers and non existant torque), but she moved quite nicely. Did some city driving (it was rush hour) and got on the highway as well (much longer test drive than the one at Hyundai). Ford did good. REAL good. I realize that this might be ONLY the V6 model, but 300 horses is still 300 horses. This thing felt waaaay faster than any V8 GT I've driven up to that point (haven't driven the new 5.0). Didn't do much in the way of handling with this car or the Genesis, but needless to say, it felt relatively responsive (for what thats worth). When we got on the highway, the salesman encouraged me to punch it a bit, so I gladly obliged him :woah: . Yes please more of that! When we got back he took me to a cleared out part of the lot, and showed me the turning radius and how tightly it turned (he said that the Ford engineers trained them to show this to customers), and I must say, again I was impressed. Did a lookover of the car, including the engine bay. Again, he knew more than most people did about the things they sell, he talked about direct injection and pointed out most of the items in the engine bay and so on. Got his card, chatted some more and went my way.
This is deffinately NOT the Mustangs of years past. It feel much more.....lively. Now the Genesis I drove was an automatic 3.8, not the manual, so take that as you will, but this thing felt MUCH faster. It honestly reminded me (power wise) of my DSM before it finally died. Had it not been for the so-so interior trim, it might have won outright right there. It honestly brought back my love-hate relationship with the Cobalt SS. I thought it was a fun to drive, but I couldnt get past the interior. Again, I realize this isn't the mighty 5.0 V8, but this thing is still a lot of fun on the dollar to drive, and still has the same transmission (if I do upgrades in the future). I still have to drive a 3.8 Genesis manual and a 2.0t manual, but something tells me the 2.0t (with its 215 hp) is going to be a bit of a disappointment compared to the 300 horses in the V6 models, so I might skip it. For now I will avoid test driving the 5.0 GT just because I know if I drive it I will spend too much on a car to get one.... Horsepower is addictive!
TL;DR: Test drove a 2011 V6 manual with 3.31 gears. Didn't think the interior was that good, but it was VERY fun to drive. Pleasantly surprised. Still no clearcut winner yet.
