The tax change?s power stems from two concurrent forces: the size of the write-off, $100,000, and the metastasizing of passenger cars into behemoths. Six thousand pounds once seemed like a reasonable demarcation between passenger vehicle and business necessity. But now, three-ton luxury cars are becoming commonplace, and they do not have to be the obvious leviathans, such as five-ton Hummers and 8,600-pound Suburbans. Chevy Trailblazers, Lincoln Aviators, Land Rover Discoveries and trendy Volkswagen Touaregs just meet the limit.
So many new models are just over 6,000 pounds that Reynolds suspects that automakers have their eyes on the tax code. A 2003 two-wheel-drive Dodge Durango weighs 6,050 pounds.
