I've had two ZS's. First was a 1.8, cracking car mate. Ran around in it for 12 months or so, never let me down. People say look for the HG, maybe I was lucky. Only thing that went wrong was the fan switch broke, but easy mend.
Then I bought a MK2 ZS180. Stonking car. Looked good, went well, handled well, reasonable on petrol. Not really sure why I sold it to be honest, it was just an itch I had to scratch I suppose. Zs's get a bad press, but I've nothing but praise for em fella (especially how cheap they are)
