My sienna was purchased with 84,000 miles on it, it has been a taxi for 3 years now and has over 370,000 miles... normal maintanence and some minor interior annoyances, but this van has been fantastic. transmission is starting to slip now, but hey, look at the hard miles it gets as a taxi....looking for another sienna to replace it now.
I Finally retired this van with just over 408,000 miles on it and it was still running strong. Transmission was getting bad but still functioning decently.... I would absolutely recommend the Sienna, Best mini van out there, PERIOD !!!
