two toyotas, no money
2001 Sienna with 98K, no rust (bought in San Antonio, 2006). Has generally behaved and allowed me to do my own work, at least until the new career kicks in.

It had started stumbling and briefly losing power with P0303 code (#3 misfire) and sometimes P0353 code (#3 coil/circuit fault). Very scary on the highway!
