This is the week that everything breaks...
Last year my car (1987 560 SEL) developed a "hiccup" when idling. I took the car in for some other work and the shop told me that the hiccup was caused by a bad ignition wire, which was replaced. Now, a year later I have a new hiccup, so I figure I might as well just replace all of them. I could find the bad one and replace it, but if this is going to continue (6 more times, I suppose) it would be simpler to just start with a fresh set.

My question is:
I see that on FastLane there are 3 brands available for my car, Bosch, PVL and Beru. Which would be best, or are the three pretty similar? If so I'll get the Bosh, since it is about $30.00 less than the other two. Are the PVL or Beru wires any better?
