The best time to go to Magic Mountain is in October, the last week they are open during the weekdays (the week of Halloween) on that Monday, Tuesday, or Wednesday.
You can replace the hybrid battery pack for $600â$2000. It will be more expensive to do it at the Toyota dealer, and the model of the car also affects price. I have had 3 Priuses in my family, and only had to replace one battery pack (200,000+ miles). I ordered a replacement battery pack from a rebuilder and had it shipped to my mechanic, who had no problems changing things out. The total cost was $1200, back in 2011.
You'll get better fuel economy and more standard tech and safety features with the Toyota Prius Prime, at a starting price that is about $6,100 less than the Volt's. The Chevy Bolt, although more expensive than the Volt, represents a leap forward in the all-electric world thanks to its 238-mile range between recharging.
