Personally I have completed tutorials for F16, Audi R8 and now Lamborghini Gallardo. Still it will be nice to finish tutorial for Ferrari , however presently lack of time. All tutorials are excellent, easy to follow and really after completion of those tutorials your skills in SolidWorks will tremendously improve.
In tutorials I have learned various advanced techniques of surface modeling in SolidWorks and thanks to those tutorials I am familiar with lot of SolidWorks features. Really brilliant tutorials.
