Careful where you park it, thieves want the catalytic converter from them as they fetch good money and they're so easy to access. I'd start with rust prevention/treatment, engine oil & filter, air filter, gearbox oil, diff oil, plugs, coolant, brake fluid and getting the calipers looked at for peace of mind. Geo and tyres obviously also. Valve adjustment is another common one to look at. Battery is probably well past it's best, very easy to change. It's well worth treating the hood to a deep clean with a colour and then sealer afterwards - renovo etc. Check boot area for damp/water. You can also easily clean out the water drain holes as they often clog up slightly. I'd also replace the pulley bearings as they're often noisy. You can buy the whole pulley wheels or just the bearings themselves for far less money. Be careful if you take it on yourself as the tension idler one is reverse threaded. Replace pulley belt at same time - they're often knackered. You can reset ecu and fuel idle trim after service just by pulling a 7.5a backup fuse under the dash - no need for codes for radio etc. Chain tensioner is a weak point as well as mentioned no doubt although not had mine done.
