As above, the book doesn't say you have to be a mechanic, just competant. It doesn't even say you need to get a stamp.
You could just write in it, or like I do, staple the receipts to the book (that way you can't loose them
).
Personally, I plan on keeping the SV for maybe 5 years. In that time, I'll be supprised if I'm still on the same engine (150k miles ish - owned from new, bought 8months back & fast approaching 16k).
I hope Rictus was right that folks expect the SV to be used
