Car choice for me has been partly a 'heart' decision rather than buying the mobile equivalent of a fridge.My Alfa has been at a local independent for over a week now (I've been on holiday), as with the OP it's started getting expensive over the last couple of years and I've probably spent as much on it as it's worth. I've started looking for a replacement (Mrs. Pm wants an automatic anyway)
BUT
I've driven a variety of hire cars over the last couple of years and still not come across anything as nice to drive as the Alfa. They are mostly ok. Even an upgrade to a BMW M525 was 'meh' after a couple of hours on a motorway. Vauxhalls are quite nice to drive, unless they have a stupid electronic handbrake. Fords are pleasant. Kias surprisingly good. Golfs didn't impress, seemed a bit cheap inside in comparison, even though they aren't. Citroens give me backache. Oh, and the last one a Hyundai i30 was one of the nicest yet.
All much of a muchness really.
@screenman 43 years, you must have seen a massive difference over that time with reliability
