The correct advice is to get a 10 year old Porsche Cayenne Turbo with 150000 km on the clock, fresh MFK and service, for half your budget: www.autoscout24.ch/4042870
Good value car in general but at that price I guess it's going to be the 1.2l petrol which, based on a hire experience in Spain a couple of years ago, is seriously underpowered (couldn't even hold 120 Km/h uphill on a motorway). Better to go for a recent used diesel imo.
The diesel/petrol argument depends on the OP's expected traveling requirements.
There are strong arguments in favour of petrol when a car is used for shorter distances etc. Especially as new small capacity petrol engines are more powerful and fuel efficient.
Octavia 1.4 gives out 150bhp, enough for most people if not towing a caravan etc, etc.
Same guarantee and service unlikely as it is the importer that underwriters this essentially.
For instance a car purchased in Germany will have a 2 year guarantee from new, whereas a car sold by the Swiss importer is usually 3 years
"Free servicing" in included in the price, so there fore in my opinion it is not free, just paid up front simply.
Whilst this doesn't explain the huge differences in price between "Swiss" cars and parallel imports, it is something to take in to consideration when making your sums.
