Don't wait to get things sorted under the warranty as there is likely to be so many get our clauses and a load of small print that makes claiming difficult.
Mine's an 02 too. I also managed to negotiate a service + cam belts. Make sure you get them to do the Variator too as this is sometimes skimped on by dealers! They're not cheap to do later.
Stone chips on front end are normal. You should see my dark green bumper.
As for a potential snag list, it really depends on how picky you want to be. There are lots of little items that could be niggly later on. I'd do a quick search in the forum to see what else you should look for.

Apart from that I can't think of other main issues. As I said, best to search for similar questions in the forum.
All the best with your purchase. May it make you as happy as mine has made me.
