Jimmmmbo!
Been here awhile...
So, here I am in SoCal in a rented black 2012 Chrysler 300 V6 rental, admittedly not optioned out, but neither is my base black 2012 Genesis.
So, these are my impressions, of which there are only 1 or 2 here:
Exterior and Performance:
Exterior: Genesis wins hands down. Sleek lines of the Genesis are simply more fashionable than the blunted lines of the 300. The G might be a bit longer, but I doubt anyone would notice the difference day-to-day. 18's on the 300 vs 17's on the G: could care less. Move up to 20's and we'll talk.
Performance: 300 responds better. There is greater throttle travel without the obvious (what I call) "holdback for better EPA MPG" on the 300 versus the G. I can merge into traffic with the 300 easier than the G in a tight situation. However, I don't let myself get into those situations in the first place very often, so it doesn't bug me much, but it's good to know it's there. That being said, the 300 definitely has what JPS in Matrix: Revolutions called a "fat *ss". The 300 on anything other than a straight line smooth road (note: LA freeways do not have "smooth roads") leads to all kinds of rear-end bucking and bouncing. This does not inspire confidence in an emergency maneuver.
Interior1:
G wins hands down. Yes, the 300 has a nice big LCD screen for all kinds of functions that make you "feel" like you have control, but you really don't. The multitude of G hard buttons may seem confusing at first, but are much more easily adapted to than any touch-screen. Also, the 300 has this weird "wide veriegation" (for lack of a better term) in their paneling that looks a lot cheaper than the G. It does have better base leather seating for soft-touch comfort, though.
Interior2:
I cannot stand the upright feel of the dash of the 300. It leads to a much more claustrophobic feeling than the G. I think this is likely enhanced by the "perceived" reduced glass area all around the cabin in the 300 versus the G.
Verdict:
Obvious. The 300 rental I'm driving is about $1500 MSRP less than the Genesis. The Genesis is the easy winner because I think the extra $1500 makes for a hugely better car.
JAO.
