Invonveniencia de reconstruir piezas como arranque, alternador.
Instalé este arranque en mi Camry 2002. Traerlo por Amazon a Caracas me costo la pieza y gastos de envío $112. Hace 8 meses se reconstruyó el arranque original con un costo de $180. Se dañó y decidí comprar uno en Amazon. Fue la mejor decisión.

Perfect OEM swap

Perfect OEM swap for an Acura RDX. It's cheap and less than 5 minutes to install. It fits snugly, and it'll keep your car running the way it should.
