He doesn't say enough about them. They are definetly not Celis LED and could be either straight replacement for a Late 2000-2003 model in which case you would need a conversion kit, or they may be designed as a facelift for the 97-early 2000 models to make them look like the later ones. Email him and ask. For a pair of staight replacement rears to give the later look to my 98 I would expect to pay around £120 that's around $216, So as things are generally a bit cheaper in the US that would fit in with the auction you are watching. LED's are usually about 50%-100% more.
I hear a good place in the states/Canada for this stuff is BVAUTO.com
