I paid €120 for first service on a 06 Astra last month: oil and filter change, top up fluids, screen wash, rotate tyres, visual check of all important items (as per handbook), new number plate and lubrication of gearchange linkage etc. I know this simple service could be done for less than €50 if you had the wherewithall, but this is something I'd happily leave to a garage- plus you want the warranty book stamped. I thought this was reasonable enough. AFAIK €60 per hour is the standard hourly labour rate for a garage these days.....
