Well with the tyres it's not included as thats just a wear and tear issue, so you pay to replace them yourself when worn. But for the Service and Maintenace I think i've found ou the answer to my own question,ÂÂÂ
I pay £15.94 a month for both included, that equals to £191.28 a year , but as i've signed up for 3 years in total for the ownership of the car to which i think I may keep it for,  thats £573.84 in total. And remember this also covers the need to replace brake pads disks and other things, so you can imagine what the price of service would be if you paid for it in cash when the car needs to go into service. Also it covers for breakdowns, if it was to ever happen so you get all that for the price.
Now I've hear people say that that they pay something like £200 odd for a service, so its actually is cheaper. Even the stealers where saying its not a money making thing, if you do it this way it does actually work out less, I can't remember the actual price of a service but it was over 200 quid!
