Finally bought a 3.5D - 2009 model.

Ending and mechanicals look good, but the interior is a little ratty.
The leather of the steering wheel is peeling, and there are many chips and scratches all over the interior (outside is pristine!). Kids!!

I am told it is a twin-turbo model.

What should I expect in terms of repairs?
Car has done 214,000 Kms, and looks well looked after.

Also, what is the difference compared to a 3D model?

Any advice appreciated.
