Purchase advice Volvo C70 Cabrio

Moin, I’m Jona and I’m from Kiel. As a student I’m looking for a car at the moment. Unfortunately, the Saab 900 II, which I received as a gift, has been smoked. However, I have been very friendly with the idea of convertible driving. And so I came across the C70, which I like much better visually. Some of them are in mobile, but not even more optimal. Criteria are + Up to 600€ + Not silver. + AHK (can they be retrofitted?) + not necessarily in Bayer n What about a sports suspension( optical reasons) recommendation? Thanks for the answers Jonah
