Fine looking grill for $50! You did a nice job cleaning it up.
Some tips I have for that style; try to avoid picking up the grill with the plastic table. Eventually that plastic will snap. If you do want to upgrade in the future you can buy a metal table from Weber for about $99.
Also, if you haven't done so, at some point you might want to remove the bolts that hold the lid bale and the two bolts that hold on the gas assist. Over time those corrode and basically rot away, it'll create rust and it's a pain to remove them and the rust could spread. I always remove them and replace with new 1/4" stainless steel nuts/bolts/washers.
And another pretty cheap upgrade that I feel is totally worth it is a new lid bale...part # 65188. It is larger and lets the lid sit at a 90 deg angle rather than leaning in towards the grill.
