My 2015 2.0 TSI Octavia VRS is due an mot soon, ive noticed all pads are low and the rear discs have a lip on them, so I've had a price from a local vag specialist and they have quoted me £500 all in for new discs and pads allround (pagid with vented front discs) oil change, oil filter and spark plugs and the mot. 

Does this seem a reasonable price? 

I'm based in Durham.

I'd say that's a pretty good price if they do genuinely use pagid pads and discs, you've got best part of £400 of parts if you buy them yourself.
