None. Its actually my first truck, or car for that matter. Only owned motorcycles until now (still do). Bought the truck for the purpose of transporting my motorbikes but am falling for the T.
1989 Toyota 4Runner that I purchased new. My Titan just replaced it as a primary vehicle.
I did keep the 4 runner as it will be a father/ kids project to restore it.
1991 Chevy S10, 2003 Toyota Matrix, 2005 Cadillac CTS-V, then went 4 years without a vehicle (living in NYC and SF has its benefits), just picked up a 2005 Titan XE in October 2014
I owned a 2003 2500 Ram Hemi. Really loved the truck however a rod went through block at 100,000 miles and Air conditioning went out on family trip across desert that was costly. I think the new Titan 2016 is the best looking full size out there but want to feel fit and finish and see quality of materials.
Currently 2013 Ram 1500 Hemi Laramie Longhorn but too many problems and not hitting 50,000km. I'm in the moment dealing with offers for a new 2015 pro-4x. I'm excited about this!!
2015 Titan Pro-4x
2013 Ram Laramie Longhorn 1500 4x4 CC - problems
2011 Ram Sport 1500 4x4 quad - needed larger cab
2007 Ford Sport Trac - bought a house wanted a full size truck
etc..........
My last truck before the Titan was a 93 Suburban. Got over 300k miles out of it so I can't complain too much, even if the TBI 350 was a gutless turd. The T is much more enjoyable to drive, that's for sure.
Had a 2004 Dodge Ram 1500 Quad Cab 2wd with the 4.7 V8 right before I got the Titan. Don't really have anything bad to say about it other than it was underpowered. The Titan has waaaaay more power and waaaaay more interior room. Won't ever look back!
