Any noted probs with these, thinking of getting a runabout and this takes my fancy as they seem to be readily available for £300 to £700. Looking for a diesel as really after a cheap as chips runaround thats also not going to do my nut on a 200 mile round commute i have to do once a week, so 1.8 should be ok. Do these break? have any weak areas? is milage an issue?
