A few days ago you asked where I bought my SP450 for $4699.00 and I gave you the name and phone # of the dealership. When you called they quoted you retail. I just talked to the sales mgr. Mark about another matter and mentioned the fact that all the 500s were gone. He says no. He has 4 left for $4999.00. Could be some uninformed person answered your call. If you are interested you might want to call again and "BE SURE" and talk to Mark Donovan. I didn't ask if they were EFI. I didn't think of it.
