Durapowers via eBay offers this Ab Crunch/Cycling Machine for $149.99 with free shipping. That's $150 off and a great price for this kind of machine. (Elsewhere, you'd pay around the same, if not more, for this kind of machine without the cycling pedals.) It features adjustable seating and a slot for phones/tablets.
These mistakes can damage your car's exterior — which could hurt its resale value.
