Great car, I had one before the 350z if you have a read of:

Unfortunately 182's can be had for peanuts these days, and as such will have probably been owned at some stage by someone on a shoe string budget, so i wouldnt recommend Ekona's advice above. The great thing about the Trophy is their numbered plaque means you can easily checkout their previous owner(s)/history to get an idea how its been treated in the past:

That's a great feature alone that shouldn't be overlooked when paying the premium for a Trophy.
Make sure its had a cambelt change (from a reputable garage, very easy to get wrong and throw out the timing!) with receipts to prove, and at this age I would expect at least a refurb of the Sachs to have been done as well by now unless its some garage queen with exceptionally low mileage.
