Mazda 6 Combi Petrol Features? Alternatives?

Hello together, in 4-5 months at the latest we need a bigger car for the offspring. Had now looked me out the Mazda 6 Kombi, because I find the for a station wagon still quite chic and he in the media also in the last 2-3 years always well got away. Annual mileage will probably be in the range 15-17k. Lots of Landstr. to work and the obligatory tours to the supermarket plus holiday trips approx. 1x per year (up to 1200km one route). My questions would be now the following At first glance there seems to be quite high discounts… 2. What features are important in addition to the standard equipment and useful for a family carriage, with which one also wants to go on holiday? Is the exclusive line worth it? 3. Is the 145 hp gasoline tank enough or is it too low-crossing (e.g. when overtaking)? 4. What alternatives are there from other manufacturers to a comparable P/L ratio with just the same s rather chic design? Look forward to your answers.
