My 1997 AWD Previa is the third one that I have owned. I previously had a 1991 and a 1994. All three have been completely trouble free, for a total of over 620K mi. The supercharger gives the 2.4 litre engine the punch of a V6, while delivering great gas mileage. I've been searching for a replacement for 5 years, but nothing made these days even comes close. The Sienna is too long, fat, low and is just not as much fun. If Toyota ever made a reasonable replacement for the Previa, I would buy it in an instance.
Supercharged mid-engine design AWD with reasonable clearance plus a car-like ride. Super well thought out interior with flip up rear seats and swiveling middle seats.
Just make them again. A hybrid version would be great.
