We bought a 1998 Porsche Boxster in Aug 2009. Serviced as required. On 9/7/10 out driving, stopped at a stop sign as we proceeded through the stop sign the engine died, white smoke came pouring out the back. Had it towed to mechanic and was informed that then motor had seized due to the ims (intermediate shaft). Car had approx 34K for mileage. Contacted Porsche America and was basically told there was nothing they could do. After researching on the web, this appears to be a pretty common problem with the 97-99 Boxsters. The cost to replace the motor with a used motor was approx 9K and they would be using the same type of motor with the same design flaw. The car has been taken to the salvage yard and we are out quite a bit of money.
