The debate of modifying the Alfa Romeo 147 is nothing short of fierce. Some say that because the current car is so Italian and has such good engineering, it should be left as it is and you should accessorize from aftermarket, and others say that because it's still pretty bare bones it can still have some improvement. Modifications, which are most common, include engine tuning, suspension upgrades, brake enhancements, and the addition of accents. The conversation usually centers on which mods provide the most bang for the buck, how mods affect reliability and resale value and whether or not some of the changes can mitigate the stock 147's known shortcomings. Also discussed is whether quality aftermarket parts are available for the 147, as the 147 is relatively rare compared to more mainstream models. Enthusiasts also often share their experiences with various modifications, and argue in favour of more subtle OEM+ style upgrades or more radical changes.
