Thanks again for the input guys.
Regarding the M3. Will I find the ride too harsh to drive day-to-day on rubbish roads? Are they any larger in the back than a TT (with respect to the coupe version). My mate has a convertible and it is cramped in the back, not that this is a huge issue as the back seats are for SWMBO and the nipper. Take that Housey!
The A3 doesn't seem to be as involving a drive in comparison to the R32 (from what I've been reading) although that might be down to a different type of buyer. I can barely believe the price difference to the Golf for pretty much an identical platform, so it does make more sense. Image eh! Saying that, I do find the A3 to be very much a generic Audi, whilst thinking the Golf does stand out.
Thanks for the suggestion but the previous MK4 Golf doesn't interest me, and that is purely down to the looks. I appreciate that it is probably just as good on the road and loads cheaper, but I only like the MK5 Golf for some reason. I would prefer a MK5 over any other actually.
I do wonder if a 335i or 330i would be un-involving, even with a manual box, but the softer, perhaps I should say, less hardcore, nature of them might be better for me in day-to-day driving. The one thing that I mentioned regarding the ST, in that all their owners love them, also holds true for the E46 M3!
As I would be trading in the two cars to buy one, a private sale M3 is not really going to be an option though. I'd love to be able to buy one from an owners/enthusiasts club, or the like, as opposed to a dealer, but I don't think that is going to be possible.
