My dream version of the Idea would be an Alfa version of the same car. Let's call it a 135. It would be an Idea underneath, just like the Lancia Musa is. The differences would be...

1.9 JTD 126 and maybe even a little more available

Six Speed gearbox

Sport suspension

Xenon headlamps

Nicer interior

Instruments in front of driver

Alfa grille and styling

Removable rear seats

Leather available

You get the Idea...

I would not buy the Musa because there was no performance improvement compared to the Idea.
