1991 Jaguar XJS 5.3 Convertible: A Buyer’s Guide to Owning a V12 Icon in Sydney
Few cars capture the spirit of grand touring quite like the 1991 Jaguar XJS 5.3 Convertible. With its silken 5.3 litre V12, long elegant bonnet, and unmistakably British character, the drop-top XJS remains one of the most desirable ways to own a piece of Jaguar’s V12 heritage. For Sydney collectors and enthusiasts, a well-sorted example is more than a weekend indulgence along the Northern Beaches or through the Blue Mountains. It is a genuine investment-grade classic.
At Classic Car Imports (CCI), we source and present rare, collector-grade vehicles for discerning buyers across Sydney and greater NSW. This guide walks you through everything worth knowing before you acquire a 1991 XJS 5.3 Convertible, from what makes the model special to what to inspect before you commit.
Why the 1991 Jaguar XJS 5.3 Convertible Is So Collectible
The Jaguar XJ-S was produced from 1975 to 1996 and carried the near-impossible task of succeeding the legendary E-Type. Where the E-Type was all sensual curves, the XJ-S embraced a sharper, more modern silhouette penned with input from aerodynamicist Malcolm Sayer. Over two decades it matured from a controversial newcomer into a bona fide classic, and today the full-fat V12 convertibles sit among the most sought-after examples of the breed.
Nineteen ninety-one is a particularly interesting year in the model’s history. It was the transition point at which the car was refreshed and the badge was simplified from “XJ-S” to “XJS.” Depending on build date, a 1991 car may be a late pre-facelift example or an early facelift model, the latter recognisable by its cleaner rear light treatment and revised detailing. Either way, the 5.3 litre V12 remains the heart of the car and the reason enthusiasts keep coming back.
Key Specifications at a Glance
- Engine: 5.3 litre naturally aspirated V12 (5,344 cc)
- Power: Approximately 274 to 291 bhp depending on specification, with the “Fireball” high-efficiency cylinder head improving output and economy
- Transmission: Three-speed automatic, with manual examples far rarer
- Top speed: Around 240 km/h (roughly 148 mph)
- 0 to 100 km/h: Approximately 8 seconds
- Body: Two-door, 2+2 convertible with a power-operated soft top
- Sought-after details: Lattice alloy wheels, full leather interior, electric hood, heated electric seats
The appeal here is not raw numbers. It is the way the V12 delivers its performance. Power arrives in a seamless, near-silent wave, and at cruising speed the XJS convertible feels effortless and refined in a way few contemporaries could match.
A Grand Tourer With Genuine Pedigree
The XJS has always attracted a certain kind of owner. Frank Sinatra famously ran one, and the model made regular appearances in film and television throughout its life, cementing its status as a symbol of relaxed, well-heeled motoring. That cultural cachet, combined with the increasing scarcity of clean V12 convertibles, is exactly why values for properly maintained examples have been climbing.
For collectors, the 5.3 V12 convertible represents the sweet spot: the most charismatic engine, the most evocative body style, and a production window that is now firmly in classic territory.
Buying a 1991 XJS 5.3 Convertible in Sydney
Sydney’s climate is kind to a car like this. Mild winters and long stretches of coastal driving make the XJS convertible a rewarding companion, whether you are heading up the Pacific Highway or simply enjoying a Sunday run with the roof down. That said, buying a thirty-plus-year-old V12 is not something to rush.
The single most important rule with any XJS is to buy on condition and history, not on price alone. A cheaper car with gaps in its service record can quickly cost far more than a well-documented example that has been properly cared for.
What to inspect before you buy
- Cooling system: The V12 runs hot by design, so a healthy radiator, water pump, and hoses are essential. Overheating history is a red flag worth investigating thoroughly.
- Service documentation: Look for a continuous paper trail, ideally with invoices, previous ownership records, and evidence of regular V12 servicing.
- Rust: Inspect the sills, wheel arches, floors, and around the windscreen. Surface corrosion can hide more serious issues.
- The hood: Check that the power-operated soft top raises, lowers, and seals correctly, and inspect the fabric for wear and leaks.
- Electrics: Test the electric seats, windows, heating, and air conditioning, all of which can be costly to put right if neglected.
- Originality: Correct Lattice alloys, matching trim, and an unmolested interior all support long-term value.
If you are not deeply familiar with the V12, a pre-purchase inspection by a marque specialist is money well spent.

Frequently Asked Questions
How much is a 1991 Jaguar XJS 5.3 Convertible worth in Australia?
Values vary considerably based on condition, mileage, originality, and documented history. Clean, well-maintained V12 convertibles command a premium over neglected examples, and prices have been trending upward as good cars become scarcer. For an accurate valuation on a specific example, speak with a classic car specialist such as Classic Car Imports.
Is the 1991 XJS a pre-facelift or facelift model?
It can be either. Nineteen ninety-one was the transition year in which the car was updated and the badge changed from “XJ-S” to “XJS.” Early 1991 cars tend to be pre-facelift, while later build dates feature the revised facelift styling, most noticeably at the rear.
What engine does the 1991 XJS 5.3 Convertible have?
It is powered by Jaguar’s 5.3 litre naturally aspirated V12, producing roughly 274 to 291 bhp depending on specification. It is prized for its smooth, quiet, and effortless power delivery rather than outright acceleration.
Are 1991 XJS V12 convertibles reliable?
When properly maintained, the V12 is a durable and rewarding engine. Reliability issues almost always stem from deferred maintenance, particularly around cooling and electrics. A car with a strong service history and regular specialist care is the key to trouble-free ownership.
What should I look for when buying an XJS in Sydney?
Prioritise cooling system health, a complete service history, the condition of the soft top, functioning electrics, and the absence of significant rust. A pre-purchase inspection by a Jaguar V12 specialist is strongly recommended before purchase.
