Does he need suspension valves and/or struts ?
Mind you, it would not surprise if the thing would lift itself once the engine was started. They are that sort of car - either go or else no-go which can be frustrating. Just as a matter of interest - with all components working well, just starting a car and letting it IDLE for half a minute, will get the car off its haunches.
There is no real need to rev the guts out of an engine. Regards Styria
