Hi Cara,
Id say to take a look at the power output of the engine rather than the actual engine size. The 1.0 tsi 115ps engine will be more powerful and more economical than any of the older 1.4’s that you’ve driven in the past. (Unless you had a 1.4 gti or blue gt model but I’m going to guess that you didn’t)
If power outputs/horsepower/PS etc don’t make much sense then I’d recommend a test drive in one of the cars you’re looking at and I think you’ll be pleasantly surprised at just how good one of those 1.0’s actually is.
I think the Ibiza wins on style although the Polo also looks good.
As far as I am aware, neither of those models are available as a 1.4 any more. It’s either a 1.0 petrol or 1.6 diesel. Both of those have similar power outputs but I’m guessing you’d be better off with the petrol.
definitely keep an eye out for ones that say 115ps in the cars description on the motability website as that’s the most powerful one although if you’re looking for something that is similar to an older 1.4 then I’d imagine a 95ps would be closer in terms of performance. I hope this was helpful ?
