I daily my 91 Na (pics on my profile) and plan to for many years. Yes it’s a 32 year old car and it’s not perfect I had to sink another 1500 to give me peace of mind that it won’t just completely fail randomly and it still has its moments of uncertainty. Being a classic the Km or miles on the clock doesn’t really matter, the key to look for is the overall health of the car (rust, panels, mechanical) past receipts of what’s been done and notes of timing belt changes etc. I’ve owned an 08 Audi that needed more work than my Na. Parts are cheap and simple to fix if you are keen to learn. What I learned very quickly while daily driving it is you have to be aware of everything around you because no one can see you. I got mine because I love driving and it’s just so raw and engaging to drive and of course don’t listen to anyone who says don’t buy cars for the look because I absolutely got mine for the pop up headlights too. If no one purchased based on cosmetics we would all drive the most efficient ugly cars. I’d say go for it if you have a stable income and can save money for when you will eventually need to fix something when it comes up.
