You don't need a cheap Lease deal or GFV to make a car right for you, you also don't need much BHP to go fast either. Some of the best Hot Hatch cars, and still the best over the last 10 years have way less BHP than the Golf R or the Civic or the Focus for that matter. Its about how they perform as a whole, compared to 0-60/0-100 times.
If you want/need/desire 4WD and 300BHP then the R ticks the box its a perfect car for this, and better than the other options in the Audi range, or other manufactures at that price point.
In 2014 (and the same now )I wanted a VAQ diff, as light a car as possible, manual, I also didn't want the brakes biased LSD system in the R, not a fan of using brakes to go forward. So a 3 door Golf GTI PP manual was the right choice FOR ME.
If you are thinking of getting a R or GTI no amount of PCP equations or GFV figures will make a car make sense, other wise we will all just drive cars on the cheapest monthlys. No amount of people on a forum will help either. If people want the R its great news, go and get the car you want im sure you would love it to bits its a great car, others have different interests and ideas of what works for them...
