Used Holden Astra review: 2001 - 2007

There's more to producing a convertible than chopping the roof off a sedan or coupe. The steel roof forms a vital part of a car's structure, giving it strength and rigidity, and that strength has to be replaced somehow once the roof is removed. Dash or scuttle shake is often a sign of a lack of strength in a soft top, and a measure of the amount of development that's gone into the body.A car that exhibits scuttle shake, evidenced when the dash area shakes or vibrates, can be a most annoying vehicle to drive. The Astra convertible is pretty good in that respect. The body is quite tight and shows no real evidence of scuttle shake, even with quite a few kilometres under its belt.Another challenge convertible designers always face is how to make the end result look good with the top raised. The Astra also fares well in this respect.The Astra sedan and coupe were good-looking cars to start with so the basics were there, and designer Bertone did a good job in slicing the roof off and producing a new roof so that it looks good with the roof up or down.The Astra's top goes up or down at the touch of a switch, or remotely by the key, and disappears under a hatch at the back. It not only works well, it is triple insulated and has an electrically-heated glass rear window so it feels much like a sedan or coupe once the roof is raised. Like all convertibles, the Astra rag top sits atop the Astra range but also comes fully equipped to ease the price pain: leather sports seats, airconditioning, cruise, trip computer, power windows and mirrors and a CD player with steering wheel controls.The engine is a 2.2-litre double overhead cam 16-valve four-cylinder producing 108kW at 5800 revs and 203Nm at 4000 revs. From 2003 there was a choice of a 2.0-litre turbo, which gave 147kW at 5600 revs and 250Nm at 1950 revs. Standard transmission is a five-speed manual with the option of a four-speed auto.With any convertible its important to listen for body rattles that might show that it's loosening with age, or more seriously, that it's suffered a crash. Make sure the roof goes up and down with no jerking or misalignment. Check that it operates with the button in the car and remotely with the key.Closely inspect the roof inside and out for damage such as tears or folds that will need repairs down the road. Body damage can also affect the smooth function of the roof, so look for ill-fitting boot lids and doors, etc.Mechanically, the Astra convertible is pretty much the same as any Astra.The 2.2-litre engine has a chain for the camshaft drive so it doesn't have to be replaced like the belt on the regular Astra.The turbo engine does have a belt, so be aware it needs to be replaced regularly. Brake wear can also be a headache on Astras, as it is on all European cars. Be prepared to replace disc rotors and brake pads quite regularly - about every 60,000km on average.The Astra convertible is well-equipped when it comes to the crunch. It has front airbags for the driver and front-seat passenger and front side airbags as well, with reinforced A-pillars and padded roll bars behind the rear seats for protection in the event of a rollover. Dynamically, it has anti-skid brakes, traction control and electronic stability control - the first time such a system was used on a Holden.
