Honestly, it doesn't have a manual but that can be fixed...
8Y / .5 A3 / S3 could get a swap done pretty 'easily'. Have to figure how many MK7 Golf R s are going to be around with their 6MT's. Before installing it get a nice beefy clutch and toss in a Wavetrac - I guarantee you will enjoy every minute of it. That said the DSG is pretty damn good, and it was the most difficult decision when I got my R
I am still hoping for the 8Y.5 RS3 here in Canada and am on the waiting list at two dealerships which fixes all the problems I have with the MK8. It takes the three items I like about the MK8 over the MK7 (rear diff, sunroof and nicer seats), adds the DAZA and removes the hatch - which has been ruined to me by the mass amount of SUV's on the road. It took one day walking down a Costco parking lot looking for my car that made me cry inside.
Honestly I am in the same boat, the market is absolutely horrid - but you can likely thank the suburban utility van craze for that.
Swapping a manual into an audi seems like a fair chore. I mean, I'm sure it could be done, but there's probably going to be a number of one off brackets to be machined for things like pedal box retainer, master cylinder mounts, and who know if the bolts for the bell housing have correctly machined holes on the engine block. One man's easy is my box of parts waiting 2 years on me and my favorite mechanic to coordinate a time when he's in town and I'm not drowning in work, lol.
I have a dsg currently and I regret it 3/4 drives. It's great on track, but has to be tuned so you can lfb. On the street, I find it between okay and annoying. I'm always thinking either "don't shift yet" or "why haven't you shifted" and then adjusting my throttle position constantly to summon the witchcraft that makes the clutches move.
The joy of this car on the street for me is the high g rotation you can easily do with the brake. It's really fun to pinch off a right hand turn and get the rear to lift a wheel, all while not making a ton of noise and being reasonably safe within street limits. With the manual this is a great opportunity to downshift to 3rd, moderate brake, then harder brake, clutch in, gear down, heel click, clutch out, and heel roll on the throttle while releasing the brake smoothly. In the dsg this is brake.... Pull lever... Power on and release. It's totally fine...really. It's fun...really. It does not give you that hero feeling though.
