It's really hard to be specific about what makes a car handle better. But yeah some general factors like track, wheelbase, aerodynamics, tyres, driver etc do make a difference.

The weight of the car isn't always good for handling. You can have a very light car like the XTR with a balanced downforce treatment and make it handle better than a Pagani Zonda which is more than 4 times the weight and power.

The gear ratios, again depend on the track design. F1 cars use different gear ratios for each track. *

A lower COD doesn't mean the car handles better. It's just a measure of how easily the car cuts through air. A lower COD will improve top speed but not necessarily handling and stability.

F1 cars are said to be the fastest machines to lap a track. But they don't run on a low COD. While cars like the Enzo and the Mclaren F1 have COD of around 0.30-0.32, the F1 cars can go all the way to 1.00 or even more.

Just remember that drag can be produced in more than 1 way. "Drag due to resistance" and "drag due to downforce".

On the whole, a good handling car will have all the factors mentioned in the opening post, in the best possible proportions.
