Get the best LC/LX you can find within your budget. If the 02 is really nice and you really want the extras it has, then it would be worth the stretch. I personally prefer 00 and newer and like the packaging in the 01 and 02 best for the money. The 98 may be a really nice value, but it is risky without seeing it, driving it, checking it over, maintenance records, etc. it is difficult to determine.
If you can be patient you should be able to find a really nice one. I did a lot of looking in the DFW area last year and was mostly disappointed with what I saw for the price. The good ones seem to go quickly leaving the left overs. I ended up providing several salesmen with what I was looking for (features, condition, price range). It worked, I was called about 100s to look at before they hit the lot. Got one in great condition in AR at a fair price, but a similar one also became available in Dallas about a week later. If I didn't get the one, I could have had another without too much difference in time. Salemen don't mind working with you if they know you are a serious buyer and understand your expectations.
