I won't buy a car if it doesn't at least have a decent amount of service history. I don't have to see every oil change receipt, but I have to see enough to know that it was taken care of. If I see a car that shows power steering, diff, transfer case, transmission, etc. services at least once during its life, it is much more likely for me to buy it. I put service history and location ahead of the ideal color combination, but not ahead of the proper packages and options.
So, for me, it isn't an added value so much as I won't consider a car that hasn't been taken care of. I looked at one a few weeks ago that the guy had multiple blackstone results - that earned some points, but it was sold before I could get to it. Just the fact that he went through the process put that car in the running.
I am also kind of leery of seeing just electronically documented oil change receipts from the same place every 5k miles, I knew a guy who paid a shop to make him 3 years worth of maintenance records - for a BMW no less. It wasn't recently, but it was within the last few years. When someone buys my vehicles, they get a file of receipts, wrinkles, oil stains and all.
