2006-2011 Infiniti G35/G37/G25 You hate to see words such as "entry level" and "compact" enter the discussion when you're considering a luxury car, but they only work to your advantage in the used market. The Infiniti G series -- Nissan's answer to BMW's 3 series -- is basically designed as the bargain version of its German counterpart. For the slight dip in prestige, however, Infiniti G buyers get a speedy rear-wheel drive, V6 with sport-tuned suspension that turns each ride into an Infiniti commercial. The best part is that you get a whole slate of models to choose from. Available in sedan, coupe and convertible, the Infiniti G can serve as a family shuttle or a zippy little weekend plaything. Granted, the latter two are basically the equivalent of a Nissan Z with more interior room, but even the little luxuries pay big dividends. -- Written by Jason Notte in Portland, Ore. >To contact the writer of this article, click here: Jason Notte. >To follow the writer on Twitter, go to http://twitter.com/notteham. >To submit a news tip, send an email to: email@example.com.
