RTR Spec 3 vs Dark Horse

Reddit, I’m in need of your opinion.

I am looking to get an RTR Spec 3 or a Dark Horse (I would put the Whipple supercharger on it) mustang. Any thoughts, opinion or feedback on this I would appreciate it.

My thoughts on evaluating the two (not in any particular order):

1. Resell value
2. Overall performance and feel
3. Wow factor
4. Quality
5. Any other thing I should consider.

Thank you.
