ummm, nothing specific really. They like drinking oil so check the oil level is up to scratch. very fussy fookers. Check paint as japs love re-painting cars!! Check for the BIMTA certificate to prove its a legit import. Also check the brakes discs and pads have plenty of meat as they arent cheap. Apart from that nothing really.
There was a recall in Japan regarding the steering box which many suffered from, and many weren't done. Ask the guy if his was one of them!
Didn't know he was looking for one, i'd sell him mine!!
