Well, with the sport car market, the price is often determined by the owner's desperation to sell rather than quality because the market is so damn small. I saw a very nice R33 GTR for $36k and the owner really needed to sell for an overseas trip. Also, with imports you have no guarantee that a $50k example is any better than a $36k example, since you don't have much chance of being able to know exactly what kind of a life the car has ever had. I say this all from personal experience since my last car (an import) didn't fetch anywhere near the premium it deserved and there was bugger all I could do about it because potential buyers in the ~$50k bracket for an import are relatively rare. Also, when someone sees a ~$35k example, expectations adjust, not only from buyers, but also from insurers who put appropriate agreed/market value ceiling prices on the cars. I personally would never get a 'market value' policy on any import for that reason as it is now so easy for them to make it look like the market value is as low as they like.
