Vauxhall Monaro & VXR: Buying guide and review (2004-2006)

Vauxhall Monaro & VXR: Buying guide and review (2004-2006) Classic and Performance Car
Way back in 2004 when the Vauxhall Monaro first arrived in the UK, its mix of big capacity V8, manual gearbox and rear-wheel drive were decidedly old-school. Today, this formula is almost completely extinct.

The latest generation of all-wheel drive turbocharged sports cars may be the surgeon’s scalpel to the Monaro’s hammer, but it’s the Monaro’s muscle car character that makes it so appealing. Relatively low sales figures and a devoted following have kept values stronger than most rivals, but they still represent one of the most affordable ways into a big V8 sportscar.
 

Which Monaro to buy?

 
The first Vauxhall Monaro arrived in 2004 offering 329bhp from its 5.7-litre Chevy V8. Effectively a rebadged Holden it was big brash and quite unlike anything else in its segment. Performance was strong with 60mph arriving in around 6 seconds, power outputs rose steadily to 377bhp for the VXR and then to 400bhp from 2005-on for the 6.0-litre versions. 

A final limited edition supercharged VXR500 was made available in the last few months of production. This 500bhp beast was capable of a 4.8 second 0-60mph time and a top speed well in excess of 180mph. All cars came fitted with a limited-slip differential as standard.

Thanks to the low-stressed nature of the small-block Chevy motor and its decades of development, there are a whole host of performance options for those who want to push up the power outputs of the ‘lesser’ models too. Superchargers, louder exhausts, intake kits and uprated brakes are all easy to source and many cars have had some form of modification carried out.

The generous dimensions of the Monaro allow four adults to travel in comfort, with a ride quality that is actually quite bearable. The early 2004 cars had softer suspension setups which made them more wallowy, but a bit more compliant over rough surfaces. 

Available solely in two-door coupe guise, there were no major changes carried out during the production run. The only noticeable difference was that the fuel tank was relocated during the 2005 model year and subsequent cars had less boot space as a result. The interior is decently built if a bit low-rent compared to German rivals, with hard-wearing switchgear.

With only 800 Monaros finding homes in the two short years of UK-bound production, it might take a while to find the exact model you want. Happily, they are all great fun, although as prices are similar across the board we would try to find one of the uprated 5.7-litre or 6.0-litre models.

Common problems

 
• Fuel consumption is heavy in most driving conditions but the extra-long gearing does aid matters on long motorway cruises.
 
• Thanks to the hefty overall mass, suspension bushes and tyres can wear out with alarming regularity. Dampers in particular take a beating. Replacing bushes and bearings can transform the handling of older cars. 
 
• The Chevy LS1 5.7-litre and LS2 6.0-litre engines are well known for their durability. A noisy cold start is normal but prolonged ticking or tappety sounds need checking. 6-litre engines can develop sticky throttle bodies leading to a slow responding accelerator pedal which can be an expensive fix.
 
• Gearboxes can be notchy and vague which is normal, but excessive play or crunching could indicate a hard life. A quick-shift kit can sharpen up the changes too.
 
• Rust can develop on the underside of the body thanks to rustproofing treatment that is more suited to a warm dry climate. Check the usual suspects such as the wheel arches, drainage holes and footwells too.
 
• Exhaust systems are commonly replaced with more free-flowing items and as long as a reputable specialist has carried out the work this should not be an issue. The same applies to any other modifications such as remapping, intakes and even supercharger kits which are popular with these cars.
 
• One recall was carried out regarding faulty side airbags. Check your particular car’s VIN number to see if it was affected. Recalls affected the VIN numbers between: 6G1VX14F84L193858 and 6G1ZX14U15L525799.

Summary and prices 

 
The Monaro offered strong value for money when it was in production and the same applies in the used market today. The earliest 329bhp cars tend to start at around £8,000 for high-milers while closer to £10,000 is the going rate for low mileage models as well as most of the more powerful VXR and 6.0-litre cars.

The very rare VXR 500 tends to command a few thousand more if you can find one. For a very similar experience you can rather search for a supercharged 6.0-litre car. 

The Monaro may be a bit of a blunt tool in today’s high tech automotive world but that relaxed power delivery and intoxicating exhaust note still mark it out as something a bit special. And no, according to many long-time owners, the allure of that rumbling V8 doesn’t wear off.
