Hi Molly,
Hope you are enjoying the 5 now that the fine weather has finally arrived.
The engine is pretty much 'bullet proof' and the chances are it just needs a basic service after being laid up after the winter. Presumably when you say under the cover, it was outside...certainly the brake discs will have 'furred up' and will clean up after a few days driving.
I would recommend to change the HT leads every 60k miles..so depending how many miles it has done since the last major service , think about this.
Also timing belts should be done around this mileage and do the water pump at the same time.
1. Engine oil and oil filter circa.. €30
2. Spark plugs " €16
3. HT Leads " €60
4. Water pump(when needed) " €25
5. Set of timing belts " €70
Certainly if your Hubby/Boyfriend is handy he can do steps 1. 2. 3. for you.
You can price all of the above items at

Hope this helps and perhaps we will see on a run during the year.
Regards John.
