Congrats, I think you'll ultimately be much happier with the van over a Rondo. :dance: I still pine for my former Sienna on occasion. My motto pre-Sienna ownership was pretty much "Death before I'll drive/own a minivan," but I soon changed my tune and learned to appreciate it. My Prius replaced it two+ years ago, and I still miss it on road trips when I have to puzzle our stuff carefully to fit it all into the trunk, lol. A 2006 Sienna also includes more standard safety features like side curtain airbags that were optional when we got our 2005 8-passsenger model back in 2005. :dance:
You could have a Toyota dealership service department look up its service history to see if there's a record of the timing belt ever being changed at a Toyota dealer's service department and also double check to see if has any recalls in need of attention. Our 2005 8-passenger Sienna had three recalls if I'm remembering correctly. One recall was for the second row center seatbelt, another was for possible corrosion of the spare tire storage hardware located underneath the van’s second row floor pan in states utilizing road salt in the winter, and the third one I’m blanking on. I'm not certain if any of those recalls are applicable for a 2006 model or if there are others affecting the 2006 model year, but definitely double check at a Toyota dealership to see if there are any outstanding recalls listed for it.
