Great responses all - thanks.
I purchased a non turbo, one owner a few years ago, with 105,000 on clock and it was a bomb. Slow as ! The lady who'd owned it only did 5 - 10 kms a day every day. Hard on a car. I won't buy this one pictured. :-)
This one I bought at 302,000 has all receipts and services up till 280,000kms incl new timing belt. Synthethic oil all it's life as it still does. But oil leak has bothered me for a while and I don't have the eyesight or garage to fix it myself. It looks easy - if I was a few decades younger. It was also giving me the drits when the Vacuum pump was running full time. The switch was dicky and they're close to $200. Luckily I spoke to the chaps in Melb (Berry) who set me straight.
This '309K' car is magnificent throughout with newish stereo and Bilsteins so I think I'll stay with it so far. I've ordered new cam seals and've spoken to a mechanic who sounds very reasonable.
Once again, thanks. I feel like I'm calling on a wealth of knowledge here and it helps.
