I know someone thinking of chopping in a 2000 1.7 Millennium Puma for a 2003/4 Sport Ka. Budget around £4K which includes £2500ish for the Puma.

The Ka is a bit slower, but a bit newer : are they reliable? Puma returning 45mpg - would the SportKa compare? Etc Etc.

A 20 mile each way commute everyday down A roads. Got to be an enjoyable drive though seeing as the Puma is such great fun round the twisties so doesn't want anything too bland.

What's the for's and against's for that kinda swap in your opinion Mr / Miss PassionFord experts?

Thanks.
