I have a 2005 Sienna with 210,000 miles. I have given it to my son who does not have much money and a new (used) car would be a struggle for him. The van is functional but needs shocks, struts, and a timing belt (and the ABS don't work). Would you just let it ride until total failure or put some money into it to keep it going? What is the outside life (mileage) expectancy for an '05 Sienna? This has been the most reliable vehicle I have ever owned (I'm 60 years old).
