I'd assume it was a 4 cylinder VEA engine? They are both 181 PS.
Well done for finding one with decent alloys, mine were quite badly kerbed and corroded. They seem vulnerable, judging by the number of discarded buckled, cracked and otherwise damaged Ixion wheels available on eBay!
My biggest concern would be that the EGR valve and cooler could cause issues. There has been at least one recall for modifications to be performed (more than one, I believe) and so you may wish to check that this car has had the necessary attention. This thread refers, and also includes a post with pictures showing how the absence of a T-piece on the top rad hose confirms at least some of this recall work has been performed...

Additionally a few of us have suffered a lesser problem where an exhaust oxygen sensor becomes sooted-up and causes a slow response error code plus the engine warning light. Apparently Volvo need to clean it and update the engine software but I still need confirmation of that. I suggest you also find out if this has been done...

It's a lovely car though!
