Welcome (nearly) to having the best car ever lol not bias at all...
What colour did you get...?
I have a new cam follower set ready to fit go mine, if you're checking how worn it is you may aswell just change it I think...
It's worth if you have someone close to you with a fault reader to plug it in and see what's happening that may of been cleared.
I have the 2010 R and 3 out of 4 doors had a faulty module, it's an easy fix but it's £250 a door to fix with labour so if some aren't working get that knocked off the price and just do the 20 minute per door free fix. The issue means that the doors open from the inside but not the outside until the inside is opened first.
You could check to see if it has an aftermarket stereo and if the steering wheel controls work if it is (I have the standard one in mine if you check the link below).
My car is completely standard as far as I'm aware and it had a full service in October (last year) and I've topped the oil up once since... Another oil change this year so all is good with mine I think.
I would assume if they lowered a
cupra r then they did other stuff as well. Check for holes under the front bumper if they had a front splitter and also make sure the boot lid can open all the way and the gas struts are not dead.
Where abouts are you based?
