Hi - I was thinking about getting either an 2k14 or 2k15 i8 and had a few questions. What kind of markup is there on these vehicles - especially with the 2016s around the corner? Im trying to gauge what type of negotiating room I have for a barely used i8 as I see a few on sites like autotrader there doesn't seem to be really much of a difference between Giga, Tera, and pulse impulse world... is it really worth 3k for blue seat belts ( terra world) or even an additional 10K for an anthracite roof (Pulse Impulse) now that the car has been out for a little bit... is it reliable? Or has anyone seen these continuously being serviced? Thanks!
