Available in a full kit or individually, the new equipment comes from Jaguar modding firm Startech and includes cosmetic touches for the exterior and interior of the luxurious saloon.
Items such as 21″ wheels, a new front end attachment, rear spoiler lip and two ‘design’ panels can be added, while aerodynamic-enhancement kit could even lower fuel consumption on the new Jaguar XJ.
There is also a new leather interior, two heated seats and a new centre console with extra storage compartments.
Startech has also added new tables capable of holding an Apple iPad and includes a Bluetooth keyboard, a modem and a high speed internet connection.
Jaguar’s luxury four-door saloon, the newest model in the reinvigorated Jaguar range, is already one of the most luxurious premium saloons on the market.
However, those wishing to modify the Jaguar XJ are advised to check their warranty to ensure the changes do not invalidate the original manufacturer warranty.
The Jaguar XJ was launched in 2010 amid rave reviews. A specially-designed armoured Jaguar XJ was even used by David Cameron on his first day as Prime Minister.
The Jaguar XJ comes with a choice of 3.0-litre diesel or 5.0-litre V8 petrol engine and is available in three trim levels as well as a range-topping ‘Supersport’ model.
Prices for the Jaguar XJ start from £55,515 for entry-level models, rising to nearly £95,000 for the V8 Supersport model.
There are also five additional option packs including a rear seat comfort pack, illumination pack, exterior sport pack, interior sport pack and an XJ speed pack, which boosts top speed from 155mph to 174mph.
