I hate you all. 
Having serious doubts about the GTi.
£330 vs £400 on PCP...is it worth it. Plus additional fuel (25mpg vs 30mpg ish). Additional insurance. Looking around £100/month extra for the R. Less boot height (we have 30kg dog who usually sits in the boot).
It's not about being able to afford it. I even have permission from my darling wife. I know I'll get badge envy in traffic ("Wish I'd bought the R...*sigh*")
£400 is getting into 335d territory too. Hmmm.
I didn't regret a GTI for the first 6 months. Then it will became a bit boring and started to wish I had the R.....then you see one and it makes you sad inside lol.
Luckily you don't see the very often. One of my personal annoyances about the GTI is the GTD, they look so similar, with the untrained eye you can't tell the difference and they are everywhere.
On the dog front, I normally put the false floor up to level with my dog, so it doesn't have the slope at the back, and she is about 35kg ish. So either car won't have an issue with that.
I you have that itch, it's inly gonna get worse.....and I know for a few of us on here, we couldn't stand that and went and get the R and chopped in the GTi
