Great, thanks to you both. This is all extremely helpful.
The service I'm overdue for is the 30k major service, per the Subaru recommended service guide. Is that really necessary? I looked over what they do and it just seems like they're doing a lot of checking, with some fluid fill ups and an oil change. Is that service really necessary? It doesn't seem like it's worth the $600 they're charging. For that price I'd rather throw on a new exhaust.
