Don,

The bolt pattern for your car is 4x114. It's doubtful that most people selling these wheels know the actual offset, just what car them came off.

Internet is a great resource...use it to find the bolt patterns of these other cars. A quick search in a volvo, saab, etc forum will give you the bolt patterns. I doubt you'll find much Euro stuff (at least BMW...the earlier 3 series was 4x100 (same size as civics and integras) and are now 5 lug.

Good luck though.
