For those of you who haven’t noticed or don’t have them, the "LOTUS" Logo Wheel Center Caps are a "snap-in replacement" for the factory plain silver center caps. You can get them from a Lotus dealer or through an on-line parts company. They cost about $30 U.S./each. They are installed by removing the wheel, snapping the old cap out through the back of the wheel, and then snapping the new Logo cap in the center! I think they add a nice finished look to any color Elan.
