The DB12 cars for me always handled as good or better and I can see where this one will improve on those even. I just haven't had enough time with the car yet and considering I haven't driven a pan car in 8 months I didn't expect to do well. Any lack of performance shown here is entirely me or bad luck.
As for durability...the lower arms are pretty much bullet proof. Only issue I had was the kingpin which a little locktite took care of.
