Buy Cinquecento – what to look for??

Hello, I would like to buy a Cinquecento and wanted to ask you what you have to pay attention to. It should already be the yellow 1.1 Sporting, which looks simply best. At Mobile.de there are some with relatively much speedometer for under 2000 € and me under 100,000 to 3000€. Do you think I should rather reach deeper into the bag or hold that for a long time? What should I pay attention to? Thanks in advance!
