help What specs does my '07 Impreza have?

[BIZKIT551]

I just bought an '07 Impreza but I cannot find what specs it has using its VIN number.
I have used a few VIN decoders and a lot of of them say invalid and some show me only half of what it is.
For example one site shows the car as a 2008 2.5L Hatchback model when in reality it just a 2007 1.5L N/A Hatchback.
I used http://www.cars101.com/subaru/vin.htm to try decode the VIN myself but the 5th position on my VIN is H which is not even talked about on that guide.
Can someone please point me to right direction please so I can find out what exact specification my car has like trim and options?

Help is always greatly appreciated.
