I’ve been shopping for a base 911 for a while. A really clean C4 just popped up and I’ve steered away from C4’s so far.
What are the differences in handling between the C2/C4? Is the front end going to plow like most AWD cars?
Next, what are the maintenance differences? This car has had the manual transmission replaced under warranty which was a pricey job (I’m guessing because of the AWD transmission). Are the transmissions more problematic than the standard C2?

I love my C4 Coupe. Handles very well and no heaviness - Feels very much like 2WD and if anything I find it pulls through aggressive corners much better than 2WD.
As far as the Front Differential, just make sure and change the front Diff fluid every 40K miles and use OEM fluid. I never had any issues with my front Diff in any of my cars.
Manual Transmission is the only way to go.

Make sure you get full PPI w/DME readout & Bore Scope Inspection. Bring results here and we can check them out - Get 3 photos of each cylinder when you Bore Scope Inspect and make sure they provide you with clear focused photos.
I prefer the Base due to Bore Scoring being seen more in the "S" 3.8L. And my personal opinion is that there is really no noticeable difference in the slightly more HP and slightly larger brakes compared to the S model
And I prefer the black Gauge Faces.
How many miles? Colors? Cold climate car?
Ask away w/future questions!

I have owned 3 C4S 2C2S & 1 C4 Cabriolet and my current C4 coupe I love the look of the widebody

Are the C4 manual transmissions more prone to failure? Are the C4’s noticeably slower?

C2 is narrow body rear vs c4 widebody rear. C2 has better steering feel and can have more playful handling once you get the hang of throttle steering a rear engine car. C4 will have more understeer but easier to save if you go too far and better in the snow. C4 will have additional maintenance for the front drive system and a little less frunk space.

C4 steering feel is markedly blunted (and not very Porsche like) compared to C2. RWD with a performance alignment feels much better than the C4 steering IMHO. The understeer in a C4 is also pretty noticeable. If you prefer wide body looks, a .1 C4/C4S can easily be converted to RWD.

I’m not especially mechanically inclined but I did it last winter. Remove front differential, remove front output shaft (driveshaft), remove front axles and install GT3 stub axles (or disassemble axles and use the disassembled stub axle). Highly recommended! Removes 70lbs of weight, transforms steering and reduces understeer with no perceptible impact on traction.

I second this statement. The only time I feel the front is when full lock under 5mph on gravel. This is my first awd car also coming from all RWD.

Anytime you ask the front wheels to do double duty with both steering forces and driving forces going through them, you create eindersteer, especially at the limit. Once your maxed out cornering grip and then add acceleration requirements, you overcome the friction that keeps the front planted and it starts to slip and push. It does make it easier to get the car thought the turn with all the tires trying to help drive it that way, but it definitely has a different feel than a RWD car.

As you are aware I have owned a few of each and notice absolutely no difference.
If anything I notice more "grab" on my C4's when driving mountain road curves

It may not be as noticeable in regular street cars but when you equip a 997 with lightweight forged wheels and lightweight PCCBs eliminating a lot of unsprung weight, it makes the difference between RWD and AWD even more noticeable.
