Just bought a '92 LS-L

Well I waited for 10 years and just picked up a '92 Silver/Black LS-L with 140,000. I've put 1,000 on it already, and it simply doesn't use oil, and it's the most powerful, stable car I've ever owned. The trans was replaced with a Subaru remanufactured one about 40,000 miles ago. I've gotten up to 25 MPG and no less than 21. The car has no spoiler and I'm not sure if I should add a factory one. Also, I put 4 TOYO FZ4 that feel smooth all the way up to 100mph. Actually, I tend to baby my cars, but it's nice to know the power is there when you want it.
