I bought them on sale for 164€. They arrived quite quickly. The plastic parts are of very good quality, identical to the original ones of the car (NISSAN XTRAIL T32 facelift of 2020). There were no installation instructions, but you can find them on YouTube. For the installation, which I did by myself (I should note that I am not a technician nor do I have any technical profession other than the DIY projects I do at home), it took me 2 to 3 hours because some of the screws with built-in washers to fit into the holes under the bodywork and attach the side steps were slightly larger, and I wasted a lot of time trying to fit them. Eventually, I took the wheel and made them slightly smaller by a few millimeters and they fit right in. First, the side skirt must be removed, which is very easy (there are videos on YouTube), and then the side step with the integrated new skirt should be adjusted.
