My '91 245 always starts on the third revolution, hot or cold, fresh tune-up or old. The '87 245 almost always starts with the touch of the key.
I always assumed it was the nature of the beast and never questioned it. The '91 is different in several regards from the '87. It gets more power from less fuel, so I don't complain.
I agree that platinum plugs (any brand) are a waste of money in a Volvo. I have Bosch platinums in the '91 245 at the moment just to try them out - no noticable difference. My favorite spark plugs are NippoDenso, but they are getting harder and harder to find. For vintage kick-start motorcycles, where you REALLY want it to start on the first kick regardless of the condition of the battery, coil, or points, I like racing platinum plugs (the center pin looks like a needle) but those are VERY expensive.
The comparison of platinum to copper was puzzling. The planinum is only plated on the tip. In theory, platinum is a good choice because it is not oxidized easily nor eroded by the arcing. No plug has platinum up the center, nor do any plugs have copper at the tip exposed to combustion and arcing. Also, relative resistance is not really an issue in spark plugs because they have a significant amount of electrical resistance by design.
