IMO you would be far better off buying the LS400 for $1500 then buying either the LS or the Aurora.The Aurora guy never got back to me, so today I'm taking a little afternoon drive to take a look at a 2005 Lincoln LS Sport with the V8. He says it needs front hubs, which come with the car. He seems like he's ready to sell, so I'll see if I can't make a deal on it if it's in nice enough shape.
That's another one of the car's I've always wanted, they're either too expensive or totally used up, not much in between.
