Sold my modded STi well over a year ago now and don't miss it. I love the Bimmer, it's so much more comfortable, cheaper to run but still has enough power to keep a smile on my face. Rear wheel drive is much more fun too.
I hear and see subarus going around all the time and i don't miss the rumble one bit.
You will get good money for your car when the right buyer comes along and will get a very good car for that money.
