Nothing at all, this car is excellent value for money given you are buying a convertible without the name tag.
Handles well of the start and engine is very quiet + smooth.
Interior + Leather is excellent. I know for a fact the company that produces the interior "Bertone" is well known as an excellent leather maker in Italy.
A few people (and myself) agree that it has the front look of a CLK mercedes convertible (only $80k cheaper) - see one and you'll know what I mean.
The rear has a Volvo look and with its strong (steel) doors gives the car a classy and safe look. Also has definite European styling.
I would have to say that I really agree with the impressed feeling that this review gave off!!!
I also own an Astra convertible and all my friends from school say they would die to have such a beautiful car!!!
