First bit of good news is if you really want a slap Nixy is just down the road
The plugs get changed at 50k so if they havent been done they may be due.
A grounding kit is worth a look although others may not agree.
Has it had a new clutch yet, several of us, myself included are a bit heavy on the clutch and have changed them around 30k
There are a few owners around you so cpompare your car to one of them. Dont let Greekman check it though, you may never stop screaming.
As a last resort, I am passing next wednesday afternoon, throw a sicky and I will have a look.
