5 door Fiesta ST? Can get them in the UK (have not seen many here), came out in 2016 or 2017, were only 3 door before that. Not as small as you may think, worth trying a newish fiesta for size to see if you think is big enough, if interested.
Plus is tax is €280 IIRC, easy enough on fuel and gets great reviews for being a fun car. Get mountune kit and brings it over 200bhp, while still keeping warranty intact.
Downsides it is less than 250bhp (but reckon would be fast enough) and could be too small.
