One of my favourite ever cars was an end of line Mk1 Focus (Black, 3 Door) with the 1.8 TDCi in it.
My mate previously when we were younger had the Mk5 Escort with the TDDI(?) in it. What an utter dog of a car that was. Impossible to get smoothly moving, shook the car to bits.
It wasn't until later on that I read somewhere that the TDCi evolved from the aforementioned Escort diesel? If so it's frankly unbelievable they were even within the same millennium of each other, never alone anything else...!
