Dunno about how long you intend to keep the R ... but my impression of the Golf involves a rental with ~80k kms on it.
Ghent CBD streets are all cobblestones & potholes, but the Golf rental was still solid & rattle-free, despite 3yrs' worth of numpty drivers mistreating it.
Wish the Redline felt as solid & rattle-free at 15k as the base rental Mk5 at 80k ...
I hope my Motorsport hangs together OK once it arrives - I have a 9yo Audi A3 turbo quattro (also APR tuned with exhaust), I test drove a demo GTS (with the Harrop 580kw kit - as an aside, stupidly fast!) but it only had 6000 odd km's and felt looser than the Audi.
I told myself it must have had a really hard life (the rear tyres were pretty fried) and the Motorsport will hang together OK - fingers crossed.
I also thought a lot about the Golf R - for me probably would've been the best option actually, but just too close to the Audi (although better in every way). Also time for another Commodore and having the Motorsport will be a little bit special. Also liking the look of the new Honda civic type R but want to do the right thing for the kids and get something with rear air vents.
