Sold my v2 redwrx wagon after 7 years ownership.
70,000 ks and 14 oil changes.
Replaced cam belt 3 years ago.
Great car and many happy times.
Seems a bit odd not seeing it parked out back but life goes on.

Mark,i would suggest you read the threads in the legacy and motor/turbo sections.

The best way to learn about something new is to do lots of reading first.
Cheers and have a happy day.
