RS4 vs IS-F
maybe you need to reconsider the maintanance costs of the two.

Also, i have not looked in the engine compartment of the IS-F. But on My S4, and the RS4, all the accessories are mounted on the back of the engine. If a water pump or an alternator goes out, the engine, transmission, and subframe must come out to get to them. As well as the dreaded hydraulic cam chain tensioners.
In the S4, not sure about the RS4, the clutch is the "fuse" of the drivetrain. It is fairly weak in order to protect the transmission and differentions from hard shifts and launches. Changing the clutch on one of these is not a pretty picture and can easily approach $3,500 to $4,000 at a dealership.
This chasis was never made to have a 4.2 V8 in it. Therefore audi made some decision to make it work that make it expensive to maintain.
Disclaimer: I own an 2007 S4, fairly modded though, and not an RS4. However, i feel the driving experience should be similar as handling should be close to the same and the engines make similar torque figures. While stock the RS4 makes 420 HP, my S4 should be making 380-390 Hp and more torque with a revlimiter of about 7,500 to 7,750.

No joke, went to Autozone last night to get some stuff to change the oil in my S4. Oil and filter only was almost $90. 10 Quarts of Castrol Syntec 5-W40 and filter with gaskets.

what kind of mods do you have and I'm real curious as to your gas mileage?

have and did.. owned a modified m3 for a bit, several preludes.. The saddest thing of all is one of my preludes that I turbo'd on a stock block head tranny etc. pretty much all stock was making 411fwhp when I finally sold it.. It was more reliable than my M3 and upkeep cost less. The only downfall was theft.
stupid of me to sell that car.. I haven't stopped kicking myself.. It was so much better than anything I've ever driven since... Of course it did cost me 20k on top of the cost of the car to get it that way

the BMW's and Audi's scare me without extended warranty.... porsche is in a leage of its own there... can't go wrong with a jap car for reliability... that was the appeal for me with the IS-F... but I don't like the way it looks... probably be a blast to drive though..

I think the Is's look amazing
I know this is an LS but this shows the elegance route taken very well. VIP FTW!

As far as My S4, it has the following:
Lightweight Wheels (19" OZ Superleggera's, roughly 19lbs a piece)
245/35/19 tires
Milltek Non-resonated Exhaust
APR Downpipes
Revo Technik Software
EVO MS V-Flow intake
Coming soon:
Lightweight battery mounted in trunk
remove spare, jack, and tools
carbon fiber hood, doors, and trunk
Wet nitrous system with custom intake manifold cooling purge system (~50 shot)
Lowered on H&R coilovers also helps reduce drag at higher speeds
The only other mod are the Hotchkis RS4 aggressive sways that help it oversteer under hard throttle a little.
