Here's a closer look at the 2015 Vauxhall Astra i SRi, a petrol-powered car with a 1.4-litre engine. This SRi trim Astra is Euro 6 compliant and has had only two previous owners. With a boot space of 351 litres, this Astra stands out, offering ample room for luggage, shopping, or anything else you need to transport. This makes it a practical choice when compared to similar vehicles.
