As everyone else has said, don't be too hasty in getting rid. I got my E89 a couple of months ago and when I test drove it it had RFTs on (19' rims). The ride was quite frankly awful, so much so that it almost stopped me from buying the car. Fortunately though, the car had recently been MOT'd and when I saw the MOT cert it had 2 advisories on for the front tyres which were near the legal limit. The trader agreed to replace the front tyres for me but I made a deal with him for 4 new non RFTs instead, as to him the cost wasn't much of a difference in buying 2 RFTs or 4 non RFT's. I took a punt with this though as I had no idea how much difference the non RFT's would change things. When I picked the car up, the difference was like night and day. It was like a different car altogether. I was amazed and very happy. So I went from not wanting to buy the car to absolutely loving it, just because of losing the RFTs. I actually like RFT's - I've had 3 Minis all of which were on RFT's, although they were 17 inch rims which is a far cry from 19's, it was just too much with the 19's and RFTs.
I've also just purchased another Mini (Coupe SD) and am prepared for the cabin rattles. I had a 6 month old Coupe SD before and it went back to the dealer several times during my ownership due to various cabin rattles. Did it bother me? No. To me it was a small price to pay for a car I loved. Mini's are renowned for rattles/creaks although I only ever had rattles in the Coupe, the other 2 Mini's I had before were fine. My E89 is 5 years old and doesn't have a single rattle.
I think I have BMW in my blood as I always end up going back to them. I try other cars but they just don't cut it for me and I go back to BMW. They are good solid cars in my opinion, the only problem I have ever had with any of them is the minor rattles in the Coupe, which the dealer always sorted, other than that they have all been bullet proof for me. I have an uncle who is an engineer at Jaguar and only the other day he said to me that the best engines out there are BMW engines.
It is of course your decision as to what you you and my opinion may not be the same as yours but I really wouldn't bolt just yet. You will be amazed by the difference non RFT's will make, I know I was. As others have said, you could change your tyres and keep the RFTs in case there are any warranty discrepancies. Even if you bought a complete brand new set of rims with non RFT's and kept your old rims and RFTs to one side, it would cost you nowhere near as much as what you'd lose if you sold up now. Or
keep your current rims, put non RFTs on and just hang on to the RFT's and get them put back on if you needed to for warranty purposes. If this is the only thing causing your uncertainty and everything else is hunky dory, there is a potential solution. If you fancy a ride up to Nottingham, come and have a go in mine and you'll see the difference
