it's just for a bit of fun, aka what would you do different to what is available now...
Personally, I'd want to make a range of smallish, front engine (probably 4 cyl), RWD/4WD cars, low weight, base model being made as a basic around-town RWD run about that is well balanced and although a little underpowered, still a fun car to drive and relatively cheap, both to buy and to run.
Next up from that would be the same basic car, but with a more powerful engine, still RWD.
Next up from that would be the same basic car again, but with a force-fed version of the mid-spec engine (probably turbo) and the option of 4wd.
All would be a modern day version of the Mk 1 and 2 Escorts.
I would also make something slightly smaller then a Falcon, powered by a bigger engine (probably a 6 cyl, maybe V6, maybe I6 in the base and mid-range versions, definately V8 in the top models), alloy block in all and strike a balance between weight and features.
Base model would be 6 cyl, rwd, up-spec would be same but with better cam/timing, intake and exhaust (sorta like AU XR6) , sports would be same as up-spec but with a turbo.
Muscle car version would start off with a basic V8, then the option of either a supercharged or Twin-turbo V8.
Of course, all would have suitable gear ratios for what they are designed for, so the base models would have a taller diff ratio and be designed for fuel econ, while the sporty models would have gear and diff ratios designed for performance.
Main difference would be that I would be following the Lotus method of achieving performance not by brute power, but by weight reduction and intelligent gearing.
