A naturally aspirated 4.2L V8, a six-speed manual, four doors, and quattro all‑wheel drive — in a shade of blue Audi barely made. That combination doesn't exist anymore, on any showroom floor, at any price.
In 2007, Audi took the 4.2‑liter V8 out of the S4 and Lamborghini's parts bin, dropped compression, raised the redline, and bolted it to a six‑speed manual. The result revved to 8,250 RPM with nothing forced — no turbo lag, no synthetic noise, just eight throttle bodies and a wall of induction sound most modern performance cars can't replicate at any price.
Audi never made another one. The B7 RS4 was the last naturally aspirated V8 in a mainstream four-door, and the last RS4 offered with a manual. Everything since has been turbocharged, and increasingly, automatic-only. This is one of the last examples of a formula that simply doesn't get built anymore — and it's finished in Sprint Blue, one of the rarer colors on the B7.
High mileage for a used car, unremarkable for a well-sorted German V8 with a full service history. This isn't a garage queen being flipped for a quick markup — it's been driven, maintained, and kept mechanically sound the entire time.
The items below aren't cosmetic. They're the exact failure points this platform is known for, and they've already been addressed — which is the whole reason to buy this RS4 instead of a lower-mileage one with a question mark hanging over it.
One of the less common colors offered on the B7 — most examples on the market today are Daytona Gray, Phantom Black, or Avus Silver.
Clutch, injectors, PCV, starter, motor mounts, control arms — the RS4's usual weak points have already been addressed, not left for the next owner.
No accidents, no reported damage. Just a car that's been driven and maintained the way an enthusiast keeps a car they actually intend to drive.
The B7's factory DRC (Dynamic Ride Control) system is a well-known failure point — this car has already been converted to Bilstein B8 shocks with H&R lowering springs, which sidesteps that issue entirely rather than patching it.
Both catalytic converters are still in place — the exhaust work is a sound and flow change, not an emissions delete. It's noticeably louder than stock and can drone at highway cruise; if you want the OEM exhaust note back, it's a straightforward swap.
In good condition for its age — it's aged well, but it is 18 years old. Expect the normal wear of a car this age: some cosmetic character, nothing structural. Serious inquiries are welcome to ask anything or arrange an inspection before buying.
