To be honest, the pre and facelift LS430 suspension is identical and they all fail in the same way. The LS460 suffers the same fate, it's a game of Russian roulette with any air suspension after 10 years or so. They can all be converted to springs, ask Steve if the one he bought from me has a good ride after conversion and I'm sure he'll say it has. I'd never buy another ageing car with air!
