Any modifications? I think this is one of the main reasons these cars may not last as long. The other being maintenance. A completely stock car with regular maintenance and service, I believe, will last 150k miles easy. As long as it isn't beat on and no mis-shifts, burnouts, etc. I think it's the mods that take life away from your motor and this isn't always the case. Depends on the extent of the mods. But generally the more HP you squeeze out of your engine the shorter the lifespan IMO.
