Anything 04+ should be on the table. In 05 they got all new electronics and hi speed can bus everywhere. If you go 05+ check the cem connector for water damage. There's a tsb and updated seal to keep water out from the cowl area. Motors are generally solid. Make sure you glove test the pcv system. Turbo is a mitsu unit that's dirt cheap to rebuild. Basically the same as a subi unit. Td03 iirc.
Electronics are the down fall. Check xemodex website for the cem troubleshooting. That's the big one that fails because of heat. I heat sinked ours. Xemodex had cracked the software, they're the only place to get modules and not pay absurd Volvo pricing.
