Sorry, just to add to that as u asked about the pro's and cons of both cars.

The Cat was just so advanced... close fitting body and undertray, ball diffs with a torque integrator that let you adjust how much drive you wanted at the front wheels, UJ driveshafts which allowed much more suspension movement, crashback front end to stop breakage. It was full of new ideas, but like I said, it took a while for people to get used to it.

The Optima mid on the other hand was much simpler, with suspension taken from the proven Optima series, shocks more upright and including the Option House shocks as standard, which at the time were the smoothest shocks around. The drive train was much simpler than the Cat's, but with many diff options. You could run any combination of ball, gear, or one way diff, front or rear.
