End of day clue perhaps ?

Not a cryptic clue but ...

SAAB first thing to work on the allotment.

Then after lunch Caterham into town for jobs and buy a spray gun. Not sure it likes hot days driven slowly in town - an odd backfire and running on when stopped.

But I got an appreciative chat from a bus driver who was towering above us.

Then the 308 again for a run. I thought I'd cracked the alarm yesterday but it took another 'blip' to start.

Finished off with the E-type down to the marina which seems to be rattling more, although the chaps admiring it did not mind. Oh and I must remember it is January 1964 - but a Dec 1963 build.

Finally, the clue. I seem to be able to make the rattle appear by pressing the brakes. So that will be my line of investigation for a while.
