What on Earth are you talking about?
3.8 Base vs Base went from 35.2k to 38k. That's an increase of $2800 raw... however the base 3.8 now has the nav that was previously part of the premium package at added cost as standard, so the EFFECTIVE increase is more like $~1500.
5.0 Rspec vs 5.0 Base went from 47.4k to 51.5k. That's a difference of $4100. Now the '14 Rspec came with the top Nav and the 17 speaker lexicon system (which have both been moved to the ultimate package on the '15). The heated steering
wheel and heated rear seat that were also standard on the RSpec are not included in either 5.0 package. If anything I was being too nice because IMO the '14RSpec would slot between the '15 5.0 and the '15 5.0 Ultimate once you take out standard evolutionary changes.
TLDR: Learn to math and learn what vitriol means while you're at it.
