ls400,maybe one of the last big cars you can buy cheaply,and run relatively cheaply,you don't seem to be everlastingly spending on them,im a bit wary of the 430,when i changed my old ls,it was a toss up when i bought mine between the two,and i erred on the side of caution,some of the suspension woes are a bit worrying,thou im sure theres alot of satisfied 430 owners,i will keep mine as long as economically viable.id like to go to a 460 if poss,just look a little more modern,or maybe a gs430,i do like a v8 or similar,might even consider rx
