I'm coming up on the end of the lease on my current 2017 Durango R/T (got it early in 2016). I've actually liked it so much I'm thinking about getting a 2019 model. I toyed with the notion of getting the SRT but I don't really want something that's even WORSE on gas than this 5.7 Hemi is (a 6.4 Hemi is going to be dreadful), not really worth it to me for only 100 extra HP. It's not been terrible on gas, but yeah I don't really want something that would be worse, and the engine is definitely lively enough for me. Another nicety with the newer model year R/T (18-19) is that they've added the SRT's updated front facia/bumper and hood w/ scoop and heat extractors that gives it a bit of a meaner looking up front stance. I may be a bit juvenile but I'm really digging it in black with the new mopar blue racing stripes they offer...I'm definitely liking this combo at the moment.
