Yes, they use refurbs. They are actually better quality than the originals! :D
The only direct replacement they change for new are the 18" styling kit alloys
Never saw this reply before collecting my car, so I asked the service guy, and he confirmed they are refurbs.
I said "So have they had any extra treatment so they dont corrode again??"
He said "Nope they are exactly the same"
I said "So will they corrode again then??"
He said "All alloy wheels corrode!! And I've never known anyone replace alloys like Lexus do, and I've worked at B*W, Audi, Merc, Saab. They all corrode but the customer just accepts it!!!"
I said "Maybe its just to do with Lexus owners having the knowledge that they can get them replaced!!"
I also asked what the warrenty was on the new wheels. He said the warrenty runs out with the original warrenty - ie. not even 12 months!!!
So my 1 week old alloys warrenty runs out TOMORROW !!!!! Thats b0110x !!!!
