Re: looking for a little honest advice...
Gonna be straight up and real here. This comes from someone who has been around cars for nearly his whole life with family in both sides of the biz (GM plant foreman, GM dealer manager)....only one time have I ever been unsuccessful in selling/trading a car and getting the new one I want at my price (2011 CTS-V Sedan, they wouldn't give me the polished wheels so I walked), and I've bought a lot of cars
All of the things in your details paragraph mean nothing. Nothing is a big modification and furthermore, no one really cares about mods adding value. In regards to the mint/no scratches, etc. Good, that's what people are looking for to give you true market value. Any other way and your hurting your best $$ value. Personally, and what I tell friends, is to focus most on your INTERIOR. That's where you can hold more value. Not many people want funky, stinky interiors, plus they cost more to fix. Seats and carpet are big $$ and nasty stench doesn't go away even with perfumes and crap. Exteriors can be waxed/polished/buffed/paintless dent. Focus on promoting that on a sale/trade rather than the exterior cleanliness.
OK, off my tangent there. Real talk, 4-5 months from now with 17-18k miles. Be happy if you can get $53k trade in. Be happy if you can get $55k private party value. These trucks are not WK1 SRTs. They aren't going to hold value like the originals. Remember, dealers are going to mark your trade up $4-6k when they sell it, that's where they make their cash while still having wiggle room. They don't make much on new. So they are going to price yours at $57-59k and be willing to accept $56k after a while if it doesn't sell to still make a $3k profit. Private party value is usually between trade in and dealer retail. I think those numbers are what you should be focusing on. Watch the market over time, and don't be surprised if they go lower. If they remain high, celebrate. Good luck.
