Should i trade my 2006 infiniti g35 sedan for a 2003 g35 coupe?

I know ive already asked this question, but it was at late hours so i dont
think it was a good time to ask it, so im basically reposting
someone offered to trade me there 2003 white infiniti g35 coupe with 122k
miles on it. I believe the only thing on this is the bose premium sound. In his
car, there are no problems (checked by my trusted mechanic) and in my car
(the 2006) the fuel reading a just a little bit off (shows a quarter tank is left
but in reality it is empty). Is this a trade you would do? Obviously im going
for looks here, but even with that in consideration would you make the
trade? will the sedan model last longer or will that just depend on how well i
take care of the car?
Thank you for your help!
