The first part is not entirely true. Well over 2/3 of Tacomas are made in Texas.
The second part is very true. They don't offer any deals on Tacomas because they sell anyway (They sell almost 3 times as many Tacomas annually in the USA than Frontiers) But Tacomas also hold their value incredibly well. See one of the posts above regarding trying to buy a 4 year old Tacoma. The MSRP of similarly equipped "off-road" models of the Frontier and Tacoma are close in price with the Tacoma costing $1-2k more but with a few more convenience options in the Tacoma. The Tacoma has a LOT more aftermarket support. The Frontier has a about 10% more ponies from the factory.
Test drive them both.
