At 12k both should be fine, though it does depend what kind of life the car has had, tyres should be good up to 18k though they would have lost a lot of their performance by then. Pads should last a bit longer.
That's good that it had the oil change at 5k (filter as well i hope) it will not have voided the warranty but you will need a stamp in the service book for 12k or it will. What i am a little concerned about is that you are considering buying one unseen, i personally would not do that.
Sorry Rudi, don't think that's true, had a call today from my friendly local stealer saying my first service is due 2yrs/12k though i'll be doing mine every 1yr/6k.
No you're not missing anything really, all 182's come with the RS manifold, not sure about all 172's. I wish i'd taken some photo's but the work done by ben (manifold match) grinds off a lot of extra material that you can actually see when you place the gasket (and the trophy has a lot!) over it...
Sorry to be a pedant here, but if anything the trophy ports seem to need more work than slightly older 182's :?: Perhaps why they are a little down on power on RR's?
