Pictures of the vehicle in question would certainly help To ascertain condition, whether it has been modified at any stage in its life beyond what it received with Lingenfelter. A lot of these cars have been Frankensteined unfortunately with mods..... Sounds like a nice car. But, I've seen cars with 172,000 miles that Look like new and I've seen cars with less than 10,000 miles that I just shake my head and can't believe that a car can be neglected in such a short amount of Miles. Not saying that is the case at all with you or your car, but that's why pictures can help out. Even with extremely low miles, 22 years can take its toll on a car, Which is why pictures can assist.
