If your plan was another scoob to replace it, then 100% makes sense to keep it IMO. If your looking for something more refined, better MPG, and german etc then fair enough.
But to replace a scoob with a scoob seems a bit daft. All Scoobs drink petrol and none of them had build qualilty or comfort in mind when they were built.
If there are certain aspects of your car you don't like as a daily driver, then chop out the bits and replace them. I'm guessing the suspension is hard to live with day to day and very low which would be a concern of mine
. So just swap that out for some OEM STI kit. Again with exhaust put the Miltek CAT back in and loose a few ponnies which you can afford and make it even quieter.
Better a devil you know and all that
