What to do?

[cjm_harris]

Alrite guys, looking for some advice...

I am currently in the process of buying a house, and will be increasing my commute from 6 miles, to 13.

I have a 306 LX, 1.9 non turbo diesel for my daily driving/commute but if I'm honest, its not great on fuel.

My choices are:...

1. Buy a HDI engine to go in mine (is this easy, straightforward enough to do?)
2. Sell my current 306, and buy a HDI
3. Buy something petrol thats a bit more fun, and still half decent economy, clio 172 or the like?

Thanks in advance guys
