Do not waste your money on that Doyusha abomination. Seriously. If you must have a Capri 1 right now, buy the Whitebox, or the Welly diecast.
If you have enough life left, wait for the upcoming Decalcas kit, which, as far as I understand, will be an injection moulded plastic kit.
Then use a Whitebox, or Welly diecast as a donor for bumpers, wheels and whatever else the rally version lacks.
As for Cortinas, or actually more correctly, Consul Cortinas, there also was a 1/16 scale kit by Frog.
Like much of the rest of Frog's lineup, it was later reissued by Novo in the Soviet Union.
