[pothole]

I think it really depends on when, as well.

To be frank, I'm not interested in almost anything currently being made. But I have a big soft spot for:

Late 80s to mid 90s Mercedes and BMW.
70s, 80s and early 90s Ferrari.
Late 60s, early 70s Alfa.

And that's about it bar the odd Jag and a few other isolated examples - a few Lambos, etc.

But if I had to pick a single brand, it would still be Porsche. Certain Porsches come closest to my ideal of what a driver's car should be. Late 80s / early 90s Mercedes a close second, but for a different kind of car - the car a pure transport and supremely engineered and fit for purpose.

I like the purity of concept and engineering integrity of certain BMWs, too.

But pretty much all of this is gone now, for me. The current stuff lacks the purity and integrity of old.
