This last weekend, i finaly broke down and tryed out the B-spec mode on GT4. I used it in the grand valley endurance race. Two hours later, i not only got my house cleened up, but i won the race too. Currently racing the Laguna 200 miles. I freakn love this! Its like that commercial for that Ronco food cooker thing. Set it and Forget it. i wonder what else i could do while this thing is running. Maby make a sanndwich. Oh the possabilties.
