Infiniti will increase its pricing on the 2009 G37 coupe. Compared to the 2008 model year , most increases are about $1000. Pricing are as follows: the standard G37 coupe is now $35,900 (up from $34,900 in 2008), G37x AWD is $38,700, G37 coupe in Journey trim is $36,650 (up from $35,650 in 2008) and the G37S in 6MT trim is priced at $37,000 (up from $36,200).
Infiniti believes that with these increased prices there is also increased value. Highway mpg goes from 24 mpg to 26 on 2009 rear wheel drive models. A new color "Moonlight white" is added to replace ivory pearl. Also, for an extra $130, 2009 models have an optional glass breakage sensor.
So, you can go to the dealer now and get a 2008 model, or pay $1000 more and wait and for a 2009 model with better fuel economy and new options.
