Does it come with a free egg fried rice?
I have no idea if i'm correct on this but most of the models he lists as being compatible are newer and as such will have the OBD-II (OBD2) socket as it was made standard by some group of politicians (the EU i think!) in the late 90s i believe.
If yours is the "not quite" OBD2 then i'd hazard a guess that it probably won't work.
Also, have you seen this bit in his listing :
The item will be shipped out within 1 working days after payment was received. The package will be sent by Singapore post airmail. Normally the estimated delivery time is 15-25 working days. If you don't receive the item after the 30 days, please contact us first!!! we will do our best to solve the delivery problem for you.
It will take 3-5 weeks to get to you so if you're happy to wait........
Alternatively, have you tried Amazon :
Volvo OBD readers on Amazon
Not sure if you'll find what you need but might be something there?
