In five years, you’ll look back at the ’99 models and think, “They were pretty simple.” But you won’t think so now. Technology is coming with a rush, and although items related to OBD II still are emerging, a lot more is coming on stream. In addition, a lot of the so-called “routine” underhood service is being complicated by new designs made for easier, faster assembly. But when they break, they may require additional special tools and longer R&R times. If nothing else, this report should convince you that there will be a lot of work to do, once these cars and trucks put on mileage.
