New manual luxury car?

You can get a new Acura TL SH-AWD 6MT.

Unfortunately Audi no longer makes a manual A6. You can get a RWD BMW 5 series with a stick, but the AWD ones are all automatic. MB, Jaguar, no manuals. Any Japanese FWD or AWD luxury sedans are automatics too - but if you concede the luxury brand you can buy a Honda Accord EX sedan (not the EX-L though) with a 6 speed, and also a Subaru Legacy. Both are four cylinders though, the 6 cylinder versions of each will only be automatic.

Bottom line - the only car that meets your criteria is the TL SH-AWD 6MT. You'd better buy it soon before it goes away, or you'll have to go to a RWD luxury car or FWD non luxury brand to keep your manual in a sedan.

EDIT - Bryson makes a point about the ILX - you can get that with a manual, but it's too small for five people. The TSX is another - but again if you're used to the TL you'll find that small I suspect. And both of those are fours also (TSX can be had with a V6 but not with a manual).

TL is the way to go.

Brand new acura ilx its cheap and is like a civic si in a tuxedo

Doesn't AUDI make an A6 Quattro with a six speed standard?
