This car is being discussed on the IS300.net forum as well. It seems that the owner doesn't know that his car is being sold on Ebay. It is a SCAM. Someone has taken the photographs from the owners website and is pretending to sell it to get cash. Look at the terms of the sale.
Terms of Sale:
Car is sold as is. Buyer must send a non- refundable deposit of $3000, has 10 days to complete transaction.
A $3000 non-refunable deposit is rediculous and is not normal.
The TRUE owner of this car is trying to get Ebay to stop the auction.
I've seen this happen 3 times so far but I'm sure it happens even more often than that.
Carpe Diem!
