Please do not take this the wrong way.
No 13 model year old W210 Designo is worth anywhere near 10k.
Clean retail is $7500 at best and that means it is nearly perfect.
It is a nice car and yours does seem to be very clean.
Contrary to popular belief, modes like bigger wheels, lowering it and other things actually lower the value.
If you are not willing to to take somewhere around $6500-$7500 then just drive it until it is worn out.
