Any chance you would consider something smaller than a 1.7, i never would have considered driving a car that size (purely for insurance reasons) a year after i passed my test, and i passed my test 13 years ago. if i had only been driving for a year at present day insurance prices 1.3 would probably be my limit.
That was my limit too when I passed my test, anything higher and the insurance would just be too much for me.
My advise would be to get something smaller, older and less cc (Fiesta, Corsa, Punto, Cinquecento, Metro etc.).
