For those looking to join the brotherhood, Microsoft’s CarPoint Web site (carpoint.msn.com) can help. The site gives price estimates and features for 267 model lines in six general categories, auto-industry news and timesaving comparison-shopping charts. You can even, if you dare, purchase a car at the site. Of course, there’s no substitute for getting behind the wheel, but CarPoint is a nice alternative to getting behind the eight ball of an aggressive salesperson.
