Hi
Nice looking car but sorry to disappoint you, assuming the picture of the engine is of the one in your car then it is a "Not the usual rubbishy mg rover k series". The four cylinder engines are known as K4 and the V6 is a K series V6 so called the KV6. It also has a Rover PG1 gearbox and everything else is Rover as well. The ZT has a lot of BMW bits although the petrol engines are all K4 or KV6.
Also the suspension is all MG/Rover - a design team from Rover spent £10m completely redesigning the suspension so it isn't the same as the earlier Honda of a similar shape.
Only letting you know before you sell the car and the buyer then pulls out because the description is wrong.
Good Luck.
James
