The episode mainly consisted of the presenters ambling round the lakes in 80s dad cars and nothing got even mildly destroyed.
My Dad had a Ford Granada same colour as the cortina on there and obviously the same shape, half wondered if it was the same car when I saw it in the first moment as the reg on my dads car was GUE690T 2.3L with a vinyl roof. I believe it to have long since been scrapped. Then I remembered when he sold it probably back in 1987 to someone he worked with they painted it gold so I wouldn’t be the one on topgear anyway then obviously the car on the show was a cortina.
Back in the early 80s my best friend at school his dad had a powder blue cortina with go faster stripe and his mum (posh two car family) had a mini clubman estate mustard yellow with the wooden back.
Then in the 90s one of my friends sisters got a mk1 fiesta in essentially brand new condition as the local collage had used it in there work shop for training so it had a full respray (beige obviously) every mechanical part had been replaced the engine had been rebuilt and all the trim and glass had been replaced, sadly no idea what happened to that one would be worth a fortune now on the condition it was in.
No one I knew had a BMW growing up, but my grandfather used to work for car dealerships so had a new car every week normally a Toyota, Ford or sometimes the odd Subaru.
