This is a true dilema. I went through this when contemplating a replacement for my '88 Grand Caravan. I just didn't think I could afford a genration II Ody, so what to buy? I was thinking Previa, but it was too wimpy and no driver's side door. The Sienna was too small, and a used one was almost as expensive as the used generation II Ody. I was looking at used DC vans or GM (no Windstar) when Honda came out with the 5.9% financing on Certified cars. I decided to pay longer than I wanted too so I could get the only real minivan choice.
If no Ody existed, I would probably buy a Chrysler under duress, wishing someone would build a reliable van that was truly on par with the Chrysler design. In other words, wishing there was an Ody!
