I see Hartmann HR8 wheels sell for $ 295 each and then i see the same r8 replica wheel on ebay and at sites like oewheelsllc.com for $ 469.00 for a set of 4. Any know the differences? Anyone buy the r8 reps from ebay or other site and if so how was the quality & finish especially compared to the quality of an oem wheel? Thanks for any info, Jim
