1) Unless Geoff's rules have changed, You are not buying from Prestige Motorsport. Geoff is a broker you buy through him. Geoff facilitates the purchase. You are probablly buying from a Auction House or Dealer in Japan.
2) When I bought my car through Geoff, it was all good - everything worked out as expected
3) It would serve no purpose to Geoff to facilitate selling you a dud, he usually checks things pretty well.
4) SEVS rules have changed so what I am saying could all be crap because most of the cars being imported now are using the 15 year ols rule.
5) Do a search on the SAU - on "Prestige Motorsport" you find a lot of information.
6) Beware of 15 year old imports - some are really good , some are really crap - I have no experience of 15 year old imports thru Prestige.
7) Geoff is a top bloke and does his best. If the car you decide on is not up to scratch because of something Goeff didn't know about, that's not his fault or problem
8) Most of the time importing is all good.
9) You must accept some risk for the good price you can cars imported from Japan
10) Sometimes accepting risk pays off... big time.
11) I would import using Geoff again if I was after a car that was on his list.
Hope that helps.
