You can’t compare dealer prices to private party sales, especially your car to the cars you posted.
The dealers cars have roughly 10k less miles, are bone stock and appear to never have been raced or modified, in any way.
Plus with the dealer, they may offer some sort of warranty on their own as well, which will attract the “regular buyer”.
Again, two different markets you’re trying to attract.
With the aftermarket parts included, it attracts a certain buyer, but they will not be interested in it at that price being an auto.
Without the aftermarket parts, it attracts a “regular buyer”, but will most likely deter them when they think that it has been raced and beat on by your typical high school kid when you mention and show what it comes with.
It is a good looking car and best of luck with the sale.
