Can't say that I have ever seen those kind of wheels on an X-Type before. Definitely unique. Not sure if I like the or not. That is a lot of money for a car that isn't worth a lot, although I see you have a 2009 and are in Seoul, so maybe it is worth more there than in the US. Personally, my favorite wheel on the X-Type has always been the OEM Arubas, but that is just me. If YOU like them, buy them. That is all that matters.

18" wheels should not be an issue provided the offset is good and the tires are not too wide or too tall. There were a few of 18" OEM wheels offered stock from Jaguar and I'm sure if you search on here a bit on some of the wheel and tires threads there are a number of aftermarket wheels that others put on without issue.
