This is interesting to say the least. The Previa had the same 2.4 L gas engine block as the Celica, mounted at a slant between the front seats. Accessories such as the AC compressor and alternator were driven by a high speed shaft and housed in the small compartment under the hood.

All engine maintenance was done by lifting off a cover between the seats or from underneath the vehicle. Rear wheel drive set up and almost perfect fore and aft weight distribution. Bomb proof transmission. I had one for 7 years and loved it.

Disadvantages - poor seats like all Toyotas for tall drivers, AC compressor fails often, bad rust trap where rear bumpers are attached to fenders.

I do know that 5 speed manual shift diesel Previa's were shipped to Europe (been in one as a taxicab). Maybe this is the real thing and he got the right engine. Otherwise getting it to fit would be a bear....

Unfortunately they went out of production and were replaced with the much more boring Sienna in the US and Canada.
