Well, the 'thing' is still there, after loads of helpful advice from this thread !! Sorry.
HBC have a sort of amnesty to tackle the problem ... think more aimed at cars parked on road though, and will take away free of charge until end of October. Son,at last, texted me to say had actually found log book !!
Coincidentally, someone swinging on bell at noon .. me not dressed and dripping nose .. not feeling at me best .. young Irish guy stood there with two colleagues in white van parked outside. Wants to know how much I want for said Fiesta ? Explains situation ... "£ 50" says I ... "not worth that" says he .. "will take away today, and will call back for logbook" Course I have to explain have to contact off-spring to see what is best. He will call back later in the week !!
Do I :-
1) Tell son to fill in log book to HBC and we, as council tax payers, get some sort of benefit from scrap car.
2) Get Irish 'gentlemen' down to £30 and let them take it away.
3) Believe in my instincts and think that some day next week the car is going to disappear
Couldn't really care less to be honest, just want the thing off me drive, but feel a little insecure just now.
