Smart as a second car

Good day, I’m currently looking for a second car. And that’s why I need a VW Bora 1.9 TDI Variant on the yard with enough power, trailer coupling, enough space in the trunk, etc. Now I need a second car for this car, which is “good and cheap”. So my first choice is a lot directly on a Smart ForTwo (petrol, diesel is again long distance, I think), which would meet at least theoretically all requirements. However, I would like to have a brief advice before, if this choice would be efficient or if I should look for a completely different car. Of course I have already listened to and looked around myself and read some things about the Smart. It came out that I should buy a Smart from 2003 onwards with little running power (under 100,000 km). Also I have some cars that would fit on this description already on the Internet, with a price of up to 2,500€, which would also correspond to my budget. I thought that up to a maximum of 2,500€, but there should be something to find, but it would be easy to lose some of them.
