Just wondering, instead of getting any garage to do it of servicing the car myself. Though the though has crossed my mind of service history, do you sign off the book yourself or do you leave it as if it hasn't been serviced? I don't think I'll be selling this car on, I'll either run it to the ground or pass/give it to family. But I'm always reading about how people do it themselves, but whats to show when they come to sell it on that they've done it? Would you write it in the offical service book or would you have a seperate book with all you own work/mods/servicing (with receipts) with it?
