Glad you are enjoying the car, I worked on some of the Trofeo Race cars from the series at the start of the season along with my partners dad who also has a Campovola grey 500 Abarth.
The engine is the stand out feature of these cars. Abarth quote 133bhp & 155lb ft as standard, though we have found the make about 150bhp & 160lb ft as standard with a simple remap getting you 160bhp & 180lb ft torque.
I see you're on the Abarth Forum, the information you get on there is very narrow with only paid up sponsors getting their products discussed, so only TMC piggy back box for tuning etc so look elsewhere for more comprehensive views.
The car has some fundamental flaws which means I would not drive one.
The steering on the road cars is very poor. It's not even worth driving the car out of sport mode as it's comically lite, and in sport mode it artificially firms up but is devoid of feel & feedback, it's like driving a car with the steering wheel is attached to the rack by bungee cords.
The gearchange is just ok, the standard 6speed box as found in the lesser 500 1.4 n/a is sweeter but the alfa sourced 5 speed in the Abarth has too long a throw and IMO the articulation of the gearstick is wrong.
The pedals are poorly designed with the accelerator pedal being set at the same height as the brake pedal meaning under braking it is lower making heal & towing near impossible unless you dislocate your ankle.
You sit way to high in the standard unsupportive seats, the Sabelts are brilliant but at £1500 way overpriced.
Then the biggest issue, suspension. The rear of the car does and will hit it's bump stops on bumpy A&B roads with little effort making the back end skittish, the Essesse kit makes it worse, shorter springs make car have approx 25mm of suspension travel making it unacceptable. The best thing you can do to the car is remove the rear bumpstops (they just pull off) as the car does not become coil bound or reach the end of the damper travel so no damage can be done.
We developed in conjunction with AVO & Pulce Racing a coil over mono tube suspension set up that greatly improves the car, though it is £1000+vat plus fitting if you don't do it yourself. There is a cheaper twin-tube (inferior) Gaz set up for about £850 iirc which has taken them 4 attempts to get the front spring rates right as 1st time I saw it fitted to a car it was completely coil bound, very poor, not impressed. Though on recent Abarth trackday using my partners dads car as AVO/Pulce demonstrator & comparing to Gaz set up on an admittedly not very testing Seighford track was little to choose between them.
It may sound like I'm bring very harsh to the car, but it does have good qualities. The aforementioned engine is a cracker. The Trofeo cars run standard engine with nothing more than the Garrett turbo from the Punto Essesse fitted and 3" turbo back exhaust system & with only 1.3bar of boost make 215-220bhp & 240lb ft & apart from people downshifting to 2nd rather than 4th spinning engine unto 10500 rpm and smashing the valve buckets there have been no failures. It's rumored engine on standard internals is good for 250+bhp which is brilliant from a 1.4 that will return 40+ mpg all day long.
The brakes are very strong though standard pad compound will fade if used with enthusiasim.
But as a standard package it's not as quick as my Trophy & therefore can't be as quick as the 200 or Megane you previously owned, but they are good fun & low down torque makes them feel quick & though you get no feedback the cars do produce very high levels of grip.
And the standard kit level is good, Blue & Me plus the Interscope soundsystem with built-in subwoofer etc.
