2005 Nissan Frontier King Cab 4dr King Cab Nismo 4WD SB (4.0L 6cyl 5A)
Great truck BUT not so good truck
 I bought this truck in 2006 and really liked it until the timing chain guides failed.  Found on the internet that this is a common problem.  There is also a tech bulletin out on it.  But Nissan would not cover the repair. $1400.00 later it is running well again.  Check the internet before you buy, there is a wealth of reliability info there.
