Hi John,
I have a bv-202E mkII, tho I have not yet determined the year of manufacture.
it has the b20 volvo gasoline 4 cylinder that is running well.
parts "seem" to be readily available, except, for 24 volt bosch distributor components.
I find it equal too or slightly better than the aktiv st4 in deep snow.
It carries a much larger payload and it seems that second gear high range is equal to the st4 in fourth in terms of ground speed.
Big Al, the operations compartment is indeed designed for
smaller, thinner, agile type folks.
The rear unit is much more spacious and easier to get in and out of.
