There's no question that it would cause additional wear on the starter, plugs, wires and maybe a few other components. Will it matter? Likely not. It's probably the difference between the starter failing at the 200K mile mark and the 150K mile mark... which for those of us who don't keep our cars for 15+ years just doesn't matter.
1. I never buy the first model year of a new car, I would rather have them sort the bugs out first.
2. If going with a brand that I don't know well, a new model, etc, I will often lease.
I leased. We'll see how this car does over 3 years. If it is a rock star then maybe I will buy one and drive for 7+ years in 2015. At that point I would assume there will be even more reliability data.
