What wheel comes with the UK version SLK 55? Is it the AMG five spoke 18" wheel? If so, that wheel is one of my favorites. I have it on my wife's SLK 350. They look great and are easy to clean. The first link, those 19" wheels are just like the standard 18" AMG multi spoke wheel that come on the USA version SLK 55. They look OK, but are tough to clean. I took mime off the first week I had my car. The second link, you're paying a premium for true AMG wheels. I have the same style wheel (in replica) 19" one piece shipped with Michelin PS 2 tires for $2550 (USD). If money isn't any issue, get the genuine AMG wheels, if it is, go with the replicas. I'm happy with mine. Good luck.
