Though the first generation Frontier could be bought with a rather weak I4 engine making just 143 horsepower, there were other options, such as the 3.3 liter V6 making 210 horsepower.
These trucks came in only standard cab at first, but King Cab was added in 1999. The 2000 Nissan Frontier was the first compact truck to come with a Crew Cab body and 4 doors.
The second generation Frontier introduced in 2005 is essentially a smaller version of the full size Nissan Titan. They are similar in exterior design, but the Frontier is smaller.
The top engine on the new midsize Frontier is a V6 making 265 horsepower. Transmission options include a 5 speed automatic and 6 speed manual.
These cars are popping up on the used truck market. The best place to buy a used Frontier truck is on eBay, where they are listed below used truck retail in most cases. You can also get some great deals on parts on there.
