What are some fast 4/6 cylinder automatic transmission cars?

Nothing from BMW, Audi/VW, or Mercedes-Benz. I don't want to have to drop out of college to fix my car. So only American/Japanese and possibly Swedish (volvo, saab I think?).. anyways, I'd like something that can do a quarter mile in about 14 seconds, nothing over 15 seconds. I'm buying the car USED, and I've got roughly a 12K$ spending limit (Actually only about 9, but I go to auctions so I'll get a good deal) anyways I'd PREFER AWD/FWD but I'm asking for fast.. so I might have to settle for a RWD. All I can come up with is a 2003 Infiniti G35, which I can get for about 10K$. I want something nice, I don't care how quick the V6 accords are, I do not want something that comes off as economical. I was looking into the RX-8, but I heard the rotary engine is inefficient, gas guzzling, unreliable, etc. Nothing older than 2002 please? I've already looked into 00-02 Camaros, they are not for me, same with mustangs. They are gas guzzlers and aren't even that nice, same MPG as the Infiniti but hey-- that's an Infiniti! No 2-seaters.. My dream car is a 350z, and I love Lancer Evolutions and Subari WRX's but I need a backseat and an automatic transmission. Anything besides the G35 that'll meet my needs? Thanks for helping out!
