Have to agree with "Il Presidente" Rob. Depending on how often you actually need to tow something, you could either buy the right car for the job i.e. you tow a lot, or if it's infrequent, hire a car or buy a cheap second car .. maybe a £1000 diesel or something to do your towing. The money you will save by not ruining the resale of value of your Abarth by fitting a tow bar (if indeed it is possible without hacking the rear spoiler/ diffuser) will pay for the hire car / second car.
Abarths weren't meant to tow ... you need to let them off their leash and have fun
