My first job was working for a very successful construction contractor in the late 80's and ALL the cars had phones

I used to get the use of quite a few cars like a BMW 325i, Saab Turbo, Golf GTi, XR2's, Cav's, Sierras

, and even a 2.0 Montego which went like a stabbed rat

I was only 18/19 when this was going on so felt pretty cool even though for the most part I was running personal errands for the bosses like taking the car for a wash/service, dropping them off
at a piss-up, taking them home
after a piss-up and driving back to the office on a Friday afternoon from the pub piss-up so they could sober-up enough to get themselves home later on
The key to being a successful business motorway driver was all in the technique back then.......sit right on their bumper with your right-turn indicator going

then if you worked in construction you could place your 'helmet' on the rear parcel shelf to alert others to your manliness in a no-nonsense busy man kinda way
There was also the GL/L etiquette.......if your were charging down the motorway and a Cavalier came up behind you with Colour-Coded bumpers then that meant it was a GL with the 2.0 engine and you had to move over to let this better person past

in fact back then cars were ALL about aspirations, you started with the bob-basic L version and looked on with admiration at those who could afford the GL or, dare I say, the Ghia version what came with 'electric mirrors' and everyfing
