04 S4
-JHM 93 Tune
-FI full exhaust
-JHM mani
nearly 180km

vs.

07 RS4
Bone Stock and Maintenance up to date.
200km
Fellow seems to have a meticulous maintenance history done. Essentially 1 owner vehicle.

Questions:

For the difference of $10,000…

Would you keep the avant and JHM stg1 it?

or

Have a Bonestock RS4

How much would you entertain the cost of an RS4 with 200km on the odo?
What maintenance items would you worry about?

I’m fairly sure I’d lose sleep over the fact that I went to a sedan from an avant…but. RS4.
