I bought my 2018 GT Sport (was the N-Line before N-line was a thing) for $4k under MSRP. The dealer had no other GTs on the lot and were happy to sell this one to me. Despite being close to a Jalopnik dream, they did not sell many...

Absolutely with all your points. I had to buy my GT Sport with 6-speed sight unseen before the dealer took delivery. I very rarely ever see a GT, let alone GT Sport.

This is the correct answer

I had it drop from a level 16 boss, but I think it is only by chance, and is based on % chance of Legendary weapon.

Elantra GT N-Line is the competitor for Civic Sport, not the Veloster N.

You get all the stars!
