I dealt with this same issue before I bought my Brdm.
to me the Brdm was the better vehicle. Larger, faster, more impressive. Seat more people inside, floats, more common parts. Normal truck axles, normal transmission, chevy 350 style engine, and a lot of choices for engine transplants.
Everything's pretty easy accessible from the top or inside.
Bad side? Twice the weight of the ferret. Harder to drive solo.
