drawback?? i would say pretty much nothing, i love that car... its fast, chick magnet, easy to mod, minimal service cost, be easy on right foot - it can give you the best milage, yes, it was better than my 4cyl Altma.
If you are plannin to keep the car for long time, then go for brand new ones, if you prefer used ones, then either go for 2005-2009 models, or 2011+ 5.0 modles. The 2010 models are waste of money, as it has got the same old juice in the new bottle. Stay away from American imported ones, and avoid buying it from used car markets. hunt on dubizzle, you can find better ones directly from genuine owner..
