No the pesky rattle is still there, although in the search so far I found £1.43 in change and a cigarette lighter
The boot is empty, there were some coins in the battery well though but they were stuck
The door pockets are empty so nothing is rattling in there
I found the cigarette lighter under the passenger seat but that was stuck fast
I have checked the seat runners there was a 5p and 1p coin in there but they seam clear now, but the rattle is still there. When the weather gets better I am going to get the seats out anyway, the last owner was a smoker and the car still needs a really deep clean to try and get rid of the smell so I'll be able to check easier with the seats out of the way.
Thanks for the help so far guys!
