I trade in my vehicles every 2 or 3 years so if that's you first year of the new G2 isn't an issue. If you plan on keeping the G2 in this launch it could be prudent to wait for the second model year. Wit that said I'm getting almost 50k on my 14 with 10k miles and loaded with every option available for trade in and that's what I would take if I wasn't trading in also. But that is without the super charger. So the supercharger is bringing up your price approximately 9k and you have the SE also which makes it very desirable.
You could get into a 14 Raptor laded for less without the supercharger. So if you keep your vehicle's for a while, wait for the 18, G2 my, or keep a 14 with the option to trade it in? IMO the g1 raptors lose approximately 5k a year on trade give or take but with mods hold their value way more stronger on trade in values and even better for private sales. Hope this helps. And that is a Score of a deal you found. IMO these trucks are just breaking in at 10k miles.
