Compliance costs will vary, fact of life. Geoff usually quotes what he thinks is compliance costs, not exact since there are so many variables - level of work required (more mods = $$), number of cars (eg traders who comply multiple cars/ if you've been there before), number of plates left, number of RAWS who can comply that model, etc etc.
For example, when I imported a car earlier this year I ended up better off as his estimate for compliance was $500 more than what I was actually charged.
