hey mate.
i work at a fairly large car dealership and i can get my work to get a RWC check done for you if you are genuinely keen on it.
I know for sure it needs a windscreen because i just had a rock hit me last week unfortunately.
i am the second owner of this vehicle in australia. the previous owner privately imported it himself from japan with only 24,000-ish-kms on it in 2004, and i bought it off him in April 2006 with 75,000-ish-kms on it. the car now has 112,000kms.
as in regards to getting it rego'd in SA, i would have to hand the plates in here in VIC, and you get a permit to drive it from VIC to SA.
hope this helps at all
if you have anymore questions please dont hesitate to contact me. i am not on here much at all anymore, so maybe send me an email to my hotmail account, or you can shoot me an SMS anytime.
cheers, hope to here from you soon.
Jarryd.
