hi ive recently bought a 1.8t mk4 gti, the only problem is it has got R36 replica alloys on :/ painted grey, and im after some standard gti alloys, is there a place i can advertise too swap these alloys? they have got really good tyres on and are in OK condition, im not looking for any money i just want a straight swap

the bloke who i bought the car off told me he paid a fair bit for the alloys and tyres.
thanks in advance
