since I have a 2004 325i I thought I would be able to post even about another brand. in purchasing another car, we are looking at two used infiniti 09 g37x's. one has 37k miles,premium pkg(wood interior trim,bose sound,multi cd,bluetooth,memory seats and steering column)no cpo,.23k left on warranty(or 2yrs).the other has 20k miles,no premium pkg,brushed metal interior trim,no cpo, 40k left on warranty,no cpo...was titled as a 'rental'*****er?,exec car?,agency rental? both cars exteriors are the same shape,color. 20k car is $500 more.which do you think is a better choice.? as an aside I am usually the only driver so not sure memory is important,usually listen to talk radio,but the wood trim is nice.thanks.
