Hey first of all welcome to Club Lupo & nice to know you want to be part of the lupo crew
Things to look out for are:
• Pedel Box in usually higher mileage Lupos
• Be aware if you test drive or buy a lupo and it seems to rev on it's own(Sounds silly) but that could be a few things like:
~Throtal Body problems
~Loss of Compression
~Brake Booster(Only going off what people have said with this one)
Other than that is just the usual:
• Rust in the Roof Track
• Rust on Arch
That's all the problems I really know about which can be major or costly, but just be sure to check the car out or take a mechanic to reassure yourself that there are no problems
The cars themselves are bullet proof aswell as the engines and they will last with the correct care
