Hi, i just bought a 1990 ls 400 for a really great price. The only thing that i didnt like about the car because it doesnt have leather seats so i dont have heated seats. Also, i dont think that i have air suspension either. Suspension is stock but how would i go to look to see if i have air suspension or not. Did lexus had that as an option or were all ls 400 had air ride. If not im not too worried about it then. Great forum by the way!
