We strongly advise considering your driving habits prior to choosing among the various fuel types. Is city driving or highway and motorway travel more common for you? What are your average miles driven per week?
Electric cars, plug-in hybrids and petrol are great for short distances. For long daily driving, electric cars are a strong choice if you can charge. If you have a daily commute over longer distances, a modern electric car can be a great choice - especially if you have access to charging at home or at work. Diesel cars can still make sense if you drive very far and don't have access to charging. Be aware that in a number of countries, cities have implemented bans on diesel engines with high emissions.
On AutoUncle, the Seat Leon ST is exclusively offered in the stationcar body style. In the UK, estates, commonly referred to as station wagons, are in high demand due to their perfect blend of driving prowess and generous space. Active families often gravitate towards these, as well as SUVs and MPVs, for their versatility.
