Mine daily driver would be a Porsche 944. Maybe a 951 Turbo, maybe its 968 descendant but more likely one of the later N/A 944 coupes - I keep going back and forth on it but the 3.0L S2 would probably be perfect although I'd probably really be happy with any 85-1/2 or later car as a DD.
I considered picking up a 944 instead of the Mustang since Turbo prices were falling into my price range at the time but I decided the Mustang would be a safer bet in the long run since I needed something I could depend on and wouldn't kill me price-wise or parts-availability-wise if it did break down and the 'Stang wouldn't require as much maintenance either. One of these days though...
If I needed something practical, like, schlep a bunch of stuff and people around, I'd probably get some big, 3800 powered GM boat. We miss our 2001 Buick LeSabre - lots of room for my long-ass legs and an actual adult could still realistically sit behind me for more than just a quick trip down the street, a huge trunk, reliable (keep an eye on that composite intake though), plenty of power for normal car duties, nice soft ride that made ****ty roads disappear but still handled competently, ate up miles on the interstate, decent sound factory stereo and it got fairly good mileage too (better than the slightly smaller-sized and slightly smaller, more-modern 3.5L engined Impala we've got now does). It did eat window regulators like candy though.
One of the Panther triplets would be pretty appealing too - if I needed something cheap tomorrow, I'd snag a P71 interceptor in a heartbeat. A Marauder would be especially sweet and a long wheel-base Town Car would be a fantastic highway cruiser.
If it's gotta be a four-door though, I'd really like a Lincoln LS. I'll take one with a 5 speed please.
