I have a gray 2013 G37x sedan with around 12,000 miles on it. It has sway bars, sport brakes, stillen S/C, carbon signal rear diffuser, oil and trans coolers, and an exhaust.

If I plan on selling the car how much do you guys think realistically it is possible to get out of it?

 

I would guess like $30,000 - $35,000 to the right person.

 

Wrong! Bought my '13 Pre-Certified G37x w/Nav with 15k for $25.8k for Devan Infiniti in CT.

 

That's going to be tough, seems like a lot of the modded cars sit awhile. I'm always a little suspect of cars that have been SC'd (no disrespect towards you) and I don't know if I will ever buy another used car with a turbo or turbo setup.

You"might" have better luck going back to OEM and parting out. Definitely more work but might be easier to recoup the bulk of your money. I know a couple guys looking for SCs, I'll probably add an oil and trans cooler eventually but you would be looking for a very specific buyer which could be hard to find.

With the mods you've done it would seem to me that $30k / $35k is probably the right ballpark though.

 

I second the part out you will likely take a hit selling it modified. Depends if the work is worth it or not. How do you like? Any 1/4 mile times or 0-60 with the stillen sc installed?

I would guess you get closer to your 35k parting out and closer to 30k keeping it as is. Mainly because you need to find the right buyer and I am of the mind most would be hesitant buying a used SC'd or Turbo'd G. Assuming it has been abused or the work may not be done up to par potential warranty issues etc.
