Right after a new car around £8/10k and had been looking at the polo gtis, these are an violist more expensive and closer to 15k. Just been to test drive my mates one and was very nice but he says they arent very good on petrol

I need something that can do 30+ mpg around town and 35/40+ on motorway. Has to say vag as I have looked at clio 200, Clio cup, mini, fiat abrath, skoda vrs. But nothing really stands out.
So have narrowed it down to the seat Ibiza for time being lol.
Looking at the cupras. 150/180ps. Look nice with a subtle drop (frost mod

)
Has anyone driven one/ own one?
Best engine/ model?
Will be dsg got use to having an auto so don't want to go back

Thanks
