I plan on getting them eventually. Being somewhat "rotund" getting in and out can be very difficult in a parking lot. The doors on the Xfire are very wide and they need to be opened up to do the "duck and dive" getting in. Two weeks ago a large truck parked next to the drivers side. They were still within their parking place, but right on the line. It just barely opened to the first detent. I did wriggle in but it was painful.

With the Lambo style doors they will open up out of the way and should make ingress/egress much easier. There is a company out in SoCal that doesn't specifically make them for the Xfire but they do for the previous gen SLK, so I think they should work. They claim to be the only one with DOT approval. They also claim you can still open the doors as normal and the process is reversible if you decide to sell and the new buyer does not want them.
