I'm in no need of one ( as far as I know), but has anyone priced one out? If we had to do this 5 yrs down the road, it'd be nice to be able to have the option of a slightly increased Kwh battery along with the software/firmware to take advantage of it. On Tesla's Model S, they seem to charge $500 per extra KWH once you are at their base battery. $10K to go from 40 to 60 KWH $15K to go from 60 to 85 KWH
The price for new Prius hybrid batteries has recently come down. They used to be priced in the US at $2985, but now for the NHW11 model (US 2001-2003 model years) it is $2299 and the NHW20 model (US 2004-current model years) is $2588.
