Totally agree with this, after 2 years in a GTI PP I took an R for a test drive and was sadly underwhelmed. I was expecting more of a step up but was just too similar to justify the outlay/exclusivity/downgrade in looks (IMO). As this was my 2nd GTI on the bounce (ED30 previous) I couldnt have had 3 performance Golfs in a row anyhoo, variety being the spice of life and all. I ordered a shadow black Focus RS in Feb, should be arriving in Nov.
Ps would be interested in the review
Were you allowed to really wind it up on the test drive? The R flexes most of its muscle above 5k revs. If I keep mine below 4k revs, it's barely quicker than a GTD driven hard. Sometimes you get an enthusiastic salesman (if you're accompanied on a test drive, and sometimes they sh!t themselves when you take it above 3k revs.
The RS will undoubtedly be a great drive and if Ford keep it a properly rare car, the residuals should be great, it is a lot thirstier than the R though (if that bothers you).
I actually took 2 out, in the first one the salesman directed me to a quiet country lane and said "Give it the beans down here". I redlined it in the first 2 gears then dropped it into third and had massive clutch slip and zero acceleration! I tried again and got same result. Salesman did know what to say. His only response was "That's why you should buy new!" . We went back to the dealership and got another which was fine.
My thoughts summarised were that the Golf R is definately faster, (as you say it's noticeable in the higher revs). It also feels more planted and I felt like I was sitting lower, which were all plusses. There is no doubt it's an awesome car, the positives didn't outweigh the negatives for me coming from a GTI PP personally. I dare say I'll be in a Mk 8 or 9 Golf R though after having a change.
Really looking good forward to the RS though, the test drive blew me away. Quite linear acceleration which didn't push you back in your seat as much as I expected and the interior isn't up to much but it just felt like the whole car has been engineered with fun in mind.
