Our answer:
Hi John,
A 2008 Lexus GS 300 used 9.8 litres/100km, which is 28.8mpg, with 232g/km of CO2. That latter figure is bad, because it means you will pay €2,350 every year just to tax the Lexus. AA membership in Ireland starts from €8.50 a month (the car is irrelevant) so it depends on how much cover you want. As to the other queries, these will be wildly varied and will require you to shop around with various insurance companies, garages and tyre-fitting outlets to get the best price.
