2 different forms of utility. I'd ask which do you Need more of? (covered rear end or uncovered rear end).
Not sure how much you know about the 'ups/downs' of 3rd gen runners yet here's a very good read:
3rd Gen 4Runner Buyer's Guide - Toyota 4Runner Forum - Largest 4Runner Forum It will mention the strong need for a new radiator, a Denso is about $100 on ebay/amazon and the plugs (ngk 2 prong are about $60/set).
Unusual to have a cracked dash on runner, never seen one like that, must have sat in the sun alot?
Is the tacoma a prerunner, access cab, double cab? don't really know the models by the looks. I've driven that truck w/a 4 liter, far peppier than the 3.4, far peppier. It can actually pull away in 35-45 mph traffic, 3.4 is an unbelievable DOG in this situation (it must be wound up to 3500+ to get any real torque going, the 4.0 doesn't need to be pushed near as hard).
On the flipside, the tacoma's price is FULLY RETAIL, I personally don't pay Full Retail, I aim for Wholesale or Person to Person pricing, I'm too much of a sucker for a Good deal!
Still, it's up to you and what you want, need, feel like spending or getting into debt (hate that with passion). Luck either way,
