Tamiya didn't include the engine details, so we have to wait for Italeri's 996 due the fall of 98.  The problem is that Italeri is less likely to include a complete engine unit just like their 993, which has an upper engine assembly that goes at the end of the chassis.

The front bumper is separate, so is the rear spoiler, which can be fixed either the up or down position.  The headlight brackets are chrome plated, all the lenses are clear.   The chassis is well done, but I'm not sure if the suspension details of the real car are as simple as the ones in the kit.  The interior has some problems.   The door panels are too shallow as in their Boxster kit even though the inner door panels are individual pieces.  The radio and air conditioner details look a little dull, too.  The stick, steering column, side brake lever and gas pedal are separate also, but the clutch and break pedals are attached to the bottom of the dashboard part.  The wheels are chrome plated, and the tires are Michelin MXX3.  They are excellent substitute for Italeri's 993 turbo kit.
