Hi Everyone i think i have found the perfect car for me.
since gs430 is the only engine suitable for LPG.
I have couple of questions, how often timing chain for this engine needs to be replaced, what issues these cars suffer 3rd gen gs and specially gs430?
Are they expensive to maintain since most of the cars are now close to 20 years mark.... what things was added into the face lift model ? Do all gs430 have vdim even first ones from 2004-2005 year 3rd gen gs.

How well they are protected from RUST?
Please tell me what everything you known i currently own rust bucket 4rd gen gs and i want to have something cheap to run maintain and to be ultra reliable and no rust and no issues.

Are the brakes of 4rd gen gs450h and gs430 same front ones 4 piston brake caliper per wheel, and is the suspention front and rear double wishbone?
