I would say go for it, that XJ is worth about 2,600-3,000 depending on the quality of the lift installed and the overall condition of it.... What are you asking for the teggy? When I was on the lookout for my XJ I spicifically didnt get a lifted one. I dont trust other people's work and such. To test for the death wobble try and find a bump that only one tire will hit (pothole or manhole cover etc) because the one sided hit should bring it out. If it wobbles, not the end of the world. Could be a bad steering stabalizer at least, but it could end up being loose suspension parts, bad shocks, springs, etc... This is why lifted trucks are sour to me, you have to chase down other people's problems lol.
