The offer, named as part of the Alfa Preferenza package and available when a car is financed using PCP, includes three years complimentary servicing for parts not affected by wear and tear.
It also comes with three years AA roadside assistance, a three-year paintwork warranty and, unlike most warranties, unlimited mileage for three years.
An eight-year anti-perforation warranty is also included in the Alfa Preferenza package. The anti-perforation warranty secures the owner against corrosion from the inside of the car.
During March 2012, Alfa Romeo will offer the package as part of a new PCP finance offer for one Alfa Giulietta model; the 1.6-litre 105bhp Lusso.
The PCP deal, which is a leasing deal with the option of buying the car after four years, is available with a £299 deposit and £299 per month charges over four years.
Alfa Romeo Giulietta Lusso versions come with climate control, rear parking sensors, Bluetooth, USB connectivity and hands-free technology.
The diesel engine returns 64.2mpg as an official fuel consumption figure and CO2 emissions are 114g/km. This puts the model in Band B of UK Vehicle Excise Duty.
The Alfa Romeo Giullieta is a five-door hatchback positioned as an upmarket rival to the Ford Focus. As a result, Alfa has equipped the Giulietta in line with higher specification Focus models.
As a result, the Alfa Romeo Giulietta costs £18,000 for entry-level models, £4,000 more than an entry-level Ford Focus, but comes with a more premium design and higher level of equipment as standard.
The Alfa Romeo Lusso model, to buy outright, is priced at £19,000 for petrol versions. The new Alfa Romeo Giulietta is on sale now at UK Alfa Romeo dealerships.
