I wouldn't even be looking at the servicing in the first two years of what will be a 9 year old (by the time the OP sells it) cars life. Any damage done to the engine in those first few years, by the time the oil was 33k thin, would be beyond reasonable and the car would have since died a death, or would have lost considerable performance, or wouldn't sound right, etc.
Granted, it's not ideal and the dealers should be punished for their deception, but FSH doesn't mean jack on a 9 year old car, because if it's been thrashed around, you could service it at half intervals, it's still a thrashed engine, gearbox, suspension, etc. I'd go with st13phil suggestion, pish them to sweeten your deal as much as you can persuade them too, then drive happily for a couple of years trouble free motoring and price your car accordingly in two-three years time, to make sure yours sells before anyone elses.
I've sold cars with only a couple of years dealer history at the beginning and self/independent servicing since those first couple of years, for book price, time and again, without issue.
