Some feedback for you:
This is a 1300 model car. The split bumpers and the low-rise engine cover confirm that.
But it has the 1500 engine power figures and the 5-speed transmission.
The rear suspension on these cars was also Macpherson strut independent, not the solid axle, trailing arm as it is in the data presently. Suprisingly, the car DOES drive true to my memory, I owned two of these, as my mid-life crisis
The wheel data is incorrect (too large) which causes the car to "float" off the ground in replays.
And I agree about the sound, although it's (again from memory) quite close, it's too bass, too loud, and too much transmission whine. These are all simply fixable in ext-config. My cars were stock exhausted and if I'm honest, not very exciting to hear, at all. Sewing machine noises, sadly.
I'll give these simple fixes a shot, and am happy to feed them back up to you if you like.
