Morris Marina, just after they were launched! I had taken and failed my first test in a Ford 100E, I blame my dad who taught me as he never told me your not supposed to just jump on the brake locking all the wheels at the emergency stop ;-).
For my retest (I was still an apprentice) one of the chaps at the garage had just taken delivery of a brand new Marina, it was just after the launch in 1971 he was a salt of the earth type and came with me to the test and generously allowed me to use his car. The examiner was so impressed he was smiling even before he got into the car, when the test was over he mentioned to the owner that he thought it a wonderful car.......to put into context the test station car park was full of old Fords and a couple of HA Vivas (and I know some of you would still prefer the HA's) ;-)
