hi adrian, what neck of the woods do you hail from?
if you look in the for sale section you will see that adam (chef_stagea) is selling a full leather interior so you need not worry about missing out on buying a car with it - just snap his up!
i don't have xanavi in mine, but i believe it is in the drivers side trim in the boot
and you can buy plenty of aftermarket HID kits that will drop straight into the standard headlight housings, alternatively buy a set of factory xenons that aren't modified and swap them in
