This reminds of an old experience back in the 60's
I was 12/13 years old or so, and the 'older lads' (14?) bought an old car to drive round the moor - it was a 'sit up and beg' Ford Popular, they paid £3 or £4 for it.
They had it about a week, and it was totally trashed - so we bought it off them for '30 bob' (£1.50 in the new money).
First job we got a hacksaw, and sawed through either side of the widescreen - these simple two cuts allowed us to pull the entire body off the chassis (told you it was well trashed).
This left us two front seats and a bare chassis behind
Next job was the throttle - it was made up of ball jointed metal rods, and some of these had fallen off, leaving the accelerator pedal doing nothing.
Easy fix - we tied a piece of string to the carburettor and ran it through where the windscreen used to be.
So it took two to drive, one working the steering, clutch, gears and brakes - and a friend in the passenger seat pulling the string to work the throttle
Needless to say it was huge fun, there was no weight to it, so it went quite well, and the back end was easy to slide round as what little weight there was, was in the front.
It actually lasted a fair few weeks, and we great fun with it - makes you wonder how you ever survived been a kid?.
