I think it really depends what you want. I think you also have to consider that once you get to this kind of price bracket you could get the new BMW 335 with 300HP or so.But I'm not sure there is a better car here. I don't think you can go far wrong with any of them. The TL has more standard toys on the inside. But keep in mind it will be replaced next year, so if you buy one now it is going to look dated within 12 months or so. The Infiniti is a great car, that has plenty of rave reviews. The BMW is an awesome driving machine, but you pay though the nose for every little extra.Take a drive in all three and see what you like. Also go to edmunds.com and read the reviews and the owner reviews.Honestly, to tell you what is best is impossible. It depends what you want from a car. I doubt you would regret either of the two you mentioned or the BMW.
