I\u2019m 43 and only have had 3 cars in my life only Corollas and Camry. I get a new one around 250k miles. They are great reliable cars that run well with basic maintenance. Only wear and tear items have I ever replaced with the exception of an alternateer on one of my corollas at around 200k miles. As long as I can keep going to 250k I will keep buying them.

Pros: great reliable cars

Vehicle: Toyota Corolla

Mileage: 402336 km

In place of the Valeo alternator I installed a Bosch VR6 120 amp alternator with a Bosch ABA alternator pulley (its 5 ribs versus 6 ribs of the VR6).

Pros: increased amperage

The Denso branded remanufactured alternator arrived from Rock Auto with a broken plastic socket. I arranged a return and replacement, but the second unit also arrived with the exact same damage. I believe the issue is with Denso's factory packaging, as the alternator is placed socket-down without cushioning. I returned the second replacement for a refund.

Cons: broken plastic socket, damaged upon arrival, poor packaging design

Vehicle: Toyota
