Leon still has all the bits on it,I've just taken the wheels off and raised the coilovers to a more user friendly level.it still has all the nice little upgrades all Leon's should have,there is a list in my for sale ad for the car. I only thing I would have for sale is a nearly new green cotton panel filter,this fits LCR etc air box as well.
As for the roof lining,its a nice thing to do,transforms the inside but its a big job and everything needs replacing properly otherwise it will rattle like mad.I fixed loads of rattles and badly fitted trims while i dont mine.It's one of those jobs that I'd say only attempt it if your confident and know what your doing,if not I'd leave it be as you can make a right mess. I washed and degreased the trims,plastic primed and used satin black spray. Uses quite a few tins though.the Leon might actually be Easyer to do tbh thinking about it.
