I'm looking to replace my 2001 Cadillac Seville with a Nissan Pathfinder, Infiniti QX4, or 4Runner, and I'd like to stay near $4000. I need something that will carry 700-1000lbs of boxes a few times a month and take occasional cross-country road trips with reasonable comfort and economy (currently getting 17/25 mpg from my Northstar V8).
What should I look out for? I know the 3.4 V6 puts out sufficient power but I'm concerned about head gaskets, warped blocks, and sludge.
Is the 2.7 the better, more dependable choice?
Are both engines belt-driven?
I haven't come across any threads on transmission issues other than aging radiators causing ATF and coolant to mix, so I trust that the automatic gearboxes are dependable.
Thanks!
