Hmm....
I had three door cars when I was a teenager up to about 30 years old, I suppose that coincided with getting hitched!
I've never really liked them since, the door tends to be too big and unwieldy to open in a tight car park space and it isn't so easy to put your coat, shopping, beers etc on the back seat, I also tend to prefer the look of a 5 door car in anything conventional eg Golf, (not in my aspirational car a Porsche Cayman, obviously!).
We were offered a fantastic deal on a 3dr Polo GTi a few years ago, so bought it, but that was a big mistake, for us, neither of us liked the impracticality of a 3 door and I didn't think it looked any better than a 5 door. Our view obviously!
Fast forward a few cars and she has a 5dr GTi Performance, manual ....
I had a 3 litre auto BMW recently and liked the auto, but overall we both prefer a manual.....
Obviously we are all different, interesting to hear other peoples preferences, but happy with our choice...!
