yea, just checked and i can get it just as 'cheap' over here now.
do you really need to change tensioners? you can get a belt for about £25 but a kit costs about £135. then there's the waterpump for about £90. + say £200 for labour, thats working out around £400!!
does my head in! i don't know wether to just leave it or spend silly money on a car not worth much more!
It depends how much you value your car, you could get anouther 40,000 miles out of the belt or it could go sooner, as you say a 12 year old isn't worth a lot you can get a good mark 3 for a £1000 or less now, If it was me I would run it till it goes then buy anouther good one & gut your old one for spares for the new one.
