Had just springs on my old 1.4. After a year, you really start to notice things have gone downhill, but I was a poor student who didn't mind the rock hard go-kart suspension for a year, on good roads it was superb. However, hit a bump on the motorway ...lets hope your passenger isn't holding a drink!
I went against the advice here as I got the work done cheapish and planned to sort out the susp again after my studies when I was earning, and did.
The difference between just springs and springs with matched dampers/shocks is pretty big. Your standard shocks will be shagged now anyway, I've got a 99 reg with about 50k on the clock, I'm starting to think about suspensions this summer, things have gotten bouncy!
