For the last 15 years I have been saying I would never buy a Ford (I had one when I was 17 for about a month!) then when I sold my BMW last year I considered a Focus ST. I drove a second hand one, then got a brand new one as a hire car for a weekend.....
I will still never buy a Ford
The current ST is horrible to drive. The turning circle is a joke, the seats are uncomfortable, the interior plastics are terrible, the build quality is rubbish. None of those are different in the RS. So what are you getting for £40+k there? A fast but sh1t car
