This sub is not as advanced as U-2511, and seems to have been a bit of a tub, and certainly "sinkable". From wiki, her displacement:
1,610 t (1,580 long tons) surfaced 1,799 t (1,771 long tons) submerged
By comparison, U-117 (3/7/2):
1,763 tonnes (1,735 long tons) surfaced 2,177 tonnes (2,143 long tons) submerged
And U-459: (3/7/2)
1,688 t (1,661 long tons) surfaced 1,932 t (1,901 long tons) submerged
Seems to me, compared to other existing German sub cards, 3/7/2 is probably more than reasonable. Also worth noting that with a 3/2/2 torpedo stat line, this will be the heaviest German "fighting sub" with a real torpedo stat line available to them in the relatively early year of 1942. I'd caution against turning this into an early version of U-2511 from a stats perspective.
All good man. 3/7/1 with a 3/2/2 is still pretty interesting.
Otherwise on SAs, I think there are a fair number of options. I like Secret Cargo (or one of the other cargo-ish SAs). The only thing I'd avoid is Wolfpack. This particular boat didn't appear to operate that way.

I'd say 10 points with these SAs. While not identical to any of them, it appears to fit nicely in the point grouping of U-117, U-25, U-505. It is slight better than most of these from a durability perspective, but doesn't have some of the more exotic SAs. Definitely not 11 when compared to U-510.

A little tanky, but the 4/5/1 boats are arguably a lot better from a durability standpoint. And of course Wolfpack boats will always dominate in the mass firepower department. That said, this is a very tough boat to vital with a single shot, and will have some application in small games with a single U-boat in play.

SUBMERGED SHOT: This unit can make Torpedo attacks against local enemy Submarines.
VITAL CARGO 5: At the end of a turn, if this unit is adjacent to an island on your opponent's side of the map, you may remove it from the game and score 5 victory points. You can only remove one unit with Vital Cargo from the game per turn.
A Type XID U-Boat, U180 had a range of more than 20000miles on the surface. Her first mission was to transport Indian opposition leader Subhas Chandra Bose to lead a axis support army against the british. Her unreliable machinery saw her only complete that single mission across the glob before conversion to dedicated transport. She was lost either by mine or malfunction on her second mission in August 1944
