We've got similar problems in buying cars. mine is only 47000 km and 131000 km, but yours is almost 250000 km. Its nice to have car with a great shape but you need to consider the after sales like warranty. Do you think you are not going to spend on that car within 2 years? My first car is 120000 miles old about 1930000 km new interior, new alloy wheels, nice body shape and metallic paint. First 3 months the car is in good condition and after that it starts giving me problem. That's why i am still waiting for someone to answer my questions about the 47000 and 131000 km old. and yours is 250000km so you need to think as you didn't mention about the under-chassis. Its better to consider buying cars in a dealer than a private. It is more expensive but without nightmare.
