The one that gives the buyer a 30% credit up to $4,000 and that can be taken off the price right at the time of sale by transferring the credit to the dealer. It took me half a dozen times at the IRS site to fill out the form, as it would often say the service isn't available now, try again later. Finally I got a Conformation on the dealer registration form but nothing by email stating that. I can supposedly go to the https://sa.www4.irs.gov/bola/ site to fill out a sale report, but want to be sure before committing to a sale at 30% off. Has anybody else done this? Do you get any emails from the IRS saying you are registered and good to go? There is absolutely no phone support and a message I sent on Friday for email support hasn't been answered.
