It depends on what needs doing, i mean definately oil, filter, plugs, maybe airfilter. The best thing to do is find where you are going to take it and then tell them what you want to do and that you want to source your own bits, problem being is that you dont know what other things need doing, i.e you might or might not need new brake pads but you wont know until its been looked at. Also if you're having it done somewhere then normally they make money on the parts so might not let you do it. I'd ring round a few places m8 but only go to RS specialists, i wouldn't advise taking it to just any ford dealers, believe me i've had my car at a ford dealers before and they're not the sharpest tools in the box if you know what i mean

Maybe some where like brooklyn fords, that sort of place

If you need any bits let me know as i work for fords and get bits cheap, especially plugs, i just payed £4.66 each for 4 cosworth platinum ones

Yeah saw that 500 for sale, bit over priced to be honest
