Requirements
Currently I am doing about 1000 miles a week and the Zeds costing me £150 a week in petrol

Looking for something with cruise control and a bit of space in it that wont break down too much.
Budget under 4k
So far on my list on not sure about are
Alfa 147 1.6 type thing - but not sure about not breaking down!
Audi A4 '98?
307 Desiel - but not sure about not breaking down!
Old BMW 3 serise?
My list sucks - need help!
