Late 80’s my mate had a Delta HF (I think), it was brilliant, fast, OMG the grip and beautiful (we all had minis and chevettes at the time).
Bad points; it rusted so badly he had a sign in the boot window. 0-60 in two body panels. The electrics were erratic at best, and it would spontaneously shed trim on a whim and it was hideously revvy on the motorway. ohh and it had an appetite for rubber that Catwoman would be proud of.
I once raced an Integrale along the A361 in my Manta GTE, it had me on the bendy bits but I’d reel it in on the straights (probably because the engine revs were making the owners ears bleed)
