Plenty of us here have been using P&G for years on our vehicles. Most cars get a good 3 pumps on the brake before you run out of vacuum. Enlarging the vacuum reservoir is also quite easy to do with some PVC pipe. Most people don't bother though since 3 pumps is normally plenty. The wear on the clutch is quite minimal if you learn the proper technique. The electronics stuff isn't an issue. I've never heard of anyone having any problems with it. If it is an issue, delete the alternator!
