As above, people are scared of driving them.
All the ones I have seen driving around are driven extremely gently.
Buy one, buy the best you can afford. Forget the really cheap ones. Buy 2007 onwards (238hp).
If you can , buy a Gen 3. These are stunning.
Do not expect to pay less than 15-16 for a really well maintained one.
I paid just under 16 for mine and it came with all the service records from the UK, verified mileage and only 22,000 miles. Other than the drop links and a few door dents, totally amazing.
I had a good look at the cheaper ones too before committing and they were rough to say the least. Engines didn't sound so good
