I have a 2007 Prius with 48k
I have a 2007 Prius with 48k miles, fuel it up once a year, but because I'm broke now haven't changed the oil or had it tuned up in 4-5 years, I've only replaced the 12v 2x... I've been in 2 accidents 2008 & 2013 and it's still running like new.
Based on what's happening with Gen 3, I feel I wouldn't be so fortunate as I've been with my white Gen 2 I wash every time before going out, which is about 1x every 20 days to only drive about 2 miles radius.
Toyotas are the frckn best!
