Some of the quarks are:
bad clutch smell when new (usually wares off after 5000 miles).
Non linear acceleration (boost spikes, bad ECU programming?)
Interior rattles (dash area)
Sticky clutch
You can determine build date by VIN I believe.
From what owners are saying it seems like most of these problems don't exist in the later build dates. Also I'm hoping that the 06 will have all of these problems solved.
My clutch smell went away at about 3000 miles. Mine has been perfect. The trip computer says I am getting 21 mpg mixed... I'm pretty heavy footed. The lowest it has read was 17.5 mpg (idiot driving). Its also been said that with the stage 1 map you get a little better mileage. They also released a map for fuel economy. (you can switch the maps with the
Cobb AP)
Because of the seats not folding I was thinking about the wagon but my wife said a 23 yr old should not have a wagon. Since we have another car and access to larger vehicles the folding seats were not that important. The wagon does have a great sunroof.
