They are easy to fit, but ideally get a friend to support the bootlid while you change them.The boot lid gas struts are very weak on my newly purchased Cinq.
Where would be best to purchase these new from? Are they fairly easy to remove and fit? Thanks
Shop4Parts is also a great place to get parts.
Also Partsworld-UK, their ebay shop tends to have more stuff than their actual website alot of the time weirdly.
I also have been using Mister-Auto quite a bit recently.
To be honest, they aren't old enough yet for parts to be hard to get really but if you struggle with anything in particular then pop up a post and we'll try help source them for you
mats, best bet is some not genuine tailored mats, plenty available - have a search on ebay.
door handles will be tricky, you only going to get 2nd hand ones now, someone might have some spare but no guarantees they will be better than yours.. Might be best to consider just sanding them back a bit and spraying them - use proper plastic primer if you do and then paint, maybe so matte clear so they aren't all shiny shiny. Just keep your eye out for breakers etc. Italian ebay is good for stuff like this though so try there and also the german ebay.
door handles, as above
