Have factory option 19" factory wheels/Conti tires on my '08 GL 320 CDI. Want to buy 18" 'stock' wheels/tires or trade my 19" set for the 18's. Perfect chance to upgrade. These tires-wheels fit any GL 2007 - 2008 (and maybe the '09s if the TPM system is compatible). 16,000 miles on 19" set, no curb rash. Photos later. 19" wheels were a $1500 extra option. Would you like to upgrade your 18's to 19's?
