Good Luck!

Riba,

Don't forget to post test results

frankly speaking this model made me automotive geek, though i never been and now I feel the more problems my s80 gives the more I learn and feel more confident to own Euro cars, as my next will be Audi.

Sounds good about the items you placed in. Keep posting the s80 challenges

Cheers! and good luck for sure.
