For new small cars the Fiesta Ecoboost is the best on the market I think...can't think of anything else I'd chose for the same price!Maybe the next gen Fiesta won't be so good and you can go for a change next time lol.
I've yet to find something that comes even close to the Fiesta's standard specs for the price.
Will check out the Ibiza online and see what a build comes up like.
Have also started looking at a BMW 1 Series Convertible or a 3 Series Hardtop convertible. Both for a budget between £11k-£15k.
