Just realized that the Kia dealer is in fact CMC. We had "issues" with them when they were the Rover dealer out on the A420. This included an ABS fault that they couldn't find/reproduce/fix until their sales guy borrowed it overnight to drive it round.

I even had the MD's car for a few days while they tried to fix the demonstrator we bought from them.

Personally I wouldn't buy another car from any CMC franchise.
