Bought a 99 wrangler from this place big mistake, before I took it off the lot I asked them to look at the 4 wheel drive system, after around a half hour they said, it was all set to go, so I drove off, I just had the transfer case replaced 2 weeks ago, now today driving down the express way, it started to jerk, check enginge light came on, if you drive over 60 mph, theset front end hops really bad, but the worst part is, they sold me this suv, with no discloser that the air bags have gone off, or that t.hey are missing, this veichile is not safe to drive down any road.
