As said above it depends how many miles you do, its not that they can't do it but you'll pay the dreaded Cossie tax on any parts that it needs. Servicing isn't expensive unless it needs major parts.
Petrol is the main thing as you really need to run it on SUL although NUL is ok on a standard car. If it was me I'd go for a ST model as they'll be newer & potentially lower miles.
Some good deals at the moment, best time to buy I'd say.
