My Mom and Dad would race to see who could identify the make, mode, and possibly year of the car the fastest. Both of them would know what it was though. I can't even tell which models modern cars are!
Triumph Stag. One of the most desirable British cars of the 1970s. However its V8 was let down by a poor cooling system which meant that the Stag came to a premature end. Still a car I would like to own (a modern radiator will fix the overheating).
