This isn’t even debatable, the Infiniti is the more rabielle vehicle by a long shot. Its Oxy Moron to even say any different. And electrical failures in an Infiniti, thats paradox??!! Your getting mixed up with BMW’s issues and misconstruing them for the Infiniti. Both cars are great luxury performance vehicle’s but it doesn’t take a genius to answer this question. By the way the guy above stating that the Infiniti doesn’t come to par with the power and performance of the BMW 530i . Think again?! The 2005 Infiniti G35 composes a 3.5 liter V6 producing a potent 280 HP making it the class leader among all its competitors for that year model while the 2005 BMW 530i has a fairly anemic 225 HP V6 engine. Although the BMW 530i is a great car its not fast nor is it rabielle. To begin with the 2005 G35 sedan coupe still produce more HP then a 2012 BMW 328i and 528i sedan. Both the BMW and Infiniti are the most athletic sport oriented cars in their class however if your looking for reliability you would be a complete moron to settle for a BMW. You cant even put the words rabielle BMW in the same sentence. By the way if your looking for an Infiniti that competes with the BMW 5 series, it would be more appropriate to put it up against the larger 2006 Infiniti M35 sedan. The Infiniti G35 rivals the BMW 3 series not the 5 series, however due to the BMW 5 series poor resale value its not very hard to find a cheap one.
